I’m going to be completely blunt, this mod stinks. I know you think that means you did what you set out to do, but you failed to do that by a long shot. I’m going to criticize what this mod does right and what it does wrong. I feel like I’m in a position to make this review simply because I’m making a mod of a similar nature.
1. The Moveset - He’s playable, but it’s very generic. There’s not much going for it. I could easily get a better experience by playing MCSonic.
2. The Sprites - You kinda hit the mark, but it looks like a very basic and uninspired version of TerminalMontage’s Sonic, which is also a very basic design. Kudos on actually making all 200+ sprites (I’m hoping you did, I haven’t opened it up in Slade yet), but that’s the only positive that I’ll give you. No real effort seems to show through the character’s design.
3. The Memes - Holy cannoli, this was a very rough way of intertwining memes into it. First off, you should know that memes expire. Second off, you should already know that the memes included have already expired. The “I like ya cut, G” Scream and Amogus have been dead for a long time, so this just comes off as very cringey and out of the loop.
4. The Inspiration - So, you mentioned how this is based off of the “Friday Night Funkin’ But Bad” Mod, but it doesn’t feel that way at all. First off, FNFBB isn’t overloaded with memes. Second off, the “But Bad” refers to the poor drawings and poor audio. There’s people that took actual effort to make super basic designs of the characters and the stages to give it an unfinished look and, on top of that, actually demastered the audio to sound really unfinished. This mod does neither of those particularly well.
For a first mod, this shows you have an understanding of how to use Slade. That’s it. I do hope you take these criticisms to heart and take it with you when you decide to take modding more seriously.
