To preface, for the past few days I couldn't really figure out how to communicate the point I wanted to make regarding the issue of the thok itself, so apologies if this post is messy as heck and not communicated clearly and well (after typing this out for a good few hours, I'm basically brain dead from how to format this and how nuanced talking about the thok is and I really just want to finalize this post. I basically thoked my brain into a paste). Also, apologies if I have happened to misinterpret what someone has said, mainly Time Gear. If I happened to misinterpret something, please correct me.
I'm going to have to partially disagree with Time Gear about the level design itself being detrimental to the thok and how all players would be naturally discouraged to even bother using it; I don't think the problem
itself is the level design to be frank nor do I believe that the thok is as punishing or unintuitive to new players as mentioned, but rather, the reason why new players are unsatisfied with the thok is because its designed right now to be more for use after running the campaign for the first time by its design. After all, Sonic is going to be the character that most players are going to choose first and I think with how thok is implemented in him that its actually designed to not be a fully viable tool for beginner players for the first playthrough because as it is, Sonic's design in the game right now is extremely good in terms of forcing the player to learn the basic toolset that they are given to complete the levels (mainly how their speed and physics work; they are forced to contend to the platforming challenges presented to them) since SRB2 controls extremely differently compared to other 3D sonic titles than what beginners are going to be used to and the instant burst of speed that the thok brings doesn't benefit a new player right off the bat both in terms of learning how to control the game and that the instant burst of speed combined with the lack of skill in controlling the game can and will inevitably lead to disaster. That isn't to say that the thok is completely useless to a beginner player nor is it fully discouraged however. The thok, unlike the sonic 3 insta-shield, clearly communicates what it can do right off the bat when the player starts using it for the first time (its basically a burst of speed forward) which allows for beginners to at least use it for certain sections of all maps and understand the proper use of the function after using it for a while (that spamming it in all moments is not a viable use of the tool due to the possibility of running into hazards and pits. That smarter, intuitave, and more calculated use of the tool is more beneficial). Then, when beginner players are done with the main campaign, with now having map knowledge, skills with the default toolset provided, and with the curiosity of what one can do with such a burst of speed against certain obstacles and the knowledge of the proper use of the thok, players are going to be more naturally drawn to experiment with the thok in order to push the game further (to be honest, I disagree that the thok is as punishing as what time gear makes it out to be where players would just not use it. People are going to see that burst of speed and naturally try to experiment with it after a first playthrough. I don't think many players would be organically taught to never ever use the thok just because they fell a lot of times into a pit or obstacle. A tool that can give a burst of speed and prior map knowledge that one can test the thok out on is basically more than enough incentive for beginner players to experiment with the thok). Basically, thok is more designed for players who at least have a solid foundation of the SRB2 physics and how they control in it which requires a least a full playthrough before players can get to that point, which I believe is the main problem since players in a first playthrough as sonic are still trying to get used to how SRB2 feels, so naturally, players are going to be disuaded from using thok to its full potential right away because, well, they can't yet. To basically sum it up, sonic is designed to be a beginner character that forces players to use the bare minimum tools before they try using the thok as the thok is more or less gated via skill that a beginner wouldn't have yet. Sonic and his thok are basically built to be replayed and not as a pure first run character.
The main problem with the thok is that by design, its not built for beginners, which combined with the levels not allowing enough experimentation with both the basekit and the thok, will force a lot of beginner players away from using it if at all in their first playthrough. Speaking of levels...
I did mention that I partially disagreed that the level design was the sole problem. The level design itself the way I see it is basically a subset of the bigger problem that I have presented. The reason I only partially disagreed with level design being the issue is that designing levels to allow players to fully utilize the thok is a good idea that would alleviate some of the issues that are present with the thok in general. I do think that SRB2 would benefit with at least some levels where it allowed for thok experimentation (basically sandbox like levels) as well as getting used to the main tool set more. Theoretically, if designed right, it would at least have players be more used to how SRB2 controls and would theoretically allow for players to know the basic usage of the thok right off the bat without gating it to a second playthrough (it wouldn't affect replayability either). So while I do disagree with the notion that level design is the sole problem, I agree that having better level design suited for learning how to use the thok would alleviate some of the problems with the thok. Then again, level design is not as easy said and done, so I'm not sure how well you can alleviate the issue solely with just level design alone.
To finish off, I will note that not everyone is going to replay sonic after their first playthrough and may not want to bother to experiment with him after their experience with the thok. I'm just saying that with the way sonic is right now, he's designed to be essentially a replay character with his thok currently.
And while unrelated, I do like the idea of different pathways being more faster and with risk, but yeah.
Also, another unrelated note, but Time Gear, you mentioned an elevator shaft in Techno Hill Zone that a player had to navigate in order to turn on the power to use the elevator. The only time you go into an elevator shaft and do just that is Egg Rock Zone act 2. There aren't any elevators that require you to do that in Techno Hill Zone afaik.
Who knew thok could have this much nuance.
