I'm honestly shocked at the current state this port is in.
We've been aware this port was in the works since 2.2 was initially around with pushback after pushback of the port supposedly utilizing things that would use the most recent version of SRB2. In retrospect I think it was probably worth to ask "why" and "what reason" but alas it is here.
I think everyone is well aware that the respective level packs mark pretty significant milestones in terms of modification for SRB2 as well as housing some pretty fun levels which technically saw the first use of elements in SRB2 like slopes and polyobjects. Stuff that we generally take for granted today with what people have been able to make for 2.2.
More towards the levels in these packs before we get into more of the technicalities; some of these levels offer fun usages of slopes, some have really creative asthetics, others are there to just look technically impressive and some are neat as an idea but otherwise aren't typically too much fun which these levels are typically ones that deviate from SRB2's core gameplay. Call it a skill issue but these deviations are probably some of the weakest levels in the pack as a whole and with all due respect, make the "completion" requirement too much of a tall order. To each their own in terms of that.
Inoffensive by itself... But there's more that make this port pretty poor in terms of how things are put together.
You can't select a pack individually in the game initially. You have to go fully through SUGOI, SUBARASHII and KIMOKAWAIII respectively in order to get to each pack. If that's not enough, the method of progression is just incredibly scuffed where at least in the SUGOI pack there are still issues where in the middle of a session, parts of the hub map don't open up unless you reload your save.
Certain levels also use 2.2 versions of enemies in place of where there were initially versions of 2.1 enemies and it kills a lot of the flow some of these older levels had, introducing problems that were never initially considered for these levels.
For some cutscenes also, the resolution for things like borders and text boxes for more elaborate ones are completely unoptimized to consider SRB2's current resolution sizes. I get it's a tall order but for something highly touted as professional, it cheapens the experience for it not being considered on top of the fact for some of them, there isn't even a skip function for them. Again, pretty egregious especially for the TLB of SUBARASHII.
I think it's been since patched out now but for whatever reason, there's an item set to only appear for 2.2.14 in the modpack... for a bunch of 2.1 levels... I'll bring this up again more genuinely; why and what for?
I want to rate this higher, especially as someone who enjoyed these level packs back in 2.1. To see these levels in a new engine and with a new level of polish that the pack deserves.
I honestly hope this stuff gets addressed as this feels like what we would see from one of those portleg things people go on about.
