Huge fan of this! The aesthetic is awesome and I find the gameplay to feel pretty nice and tight (the acceleration and box bouncing especially feel much better after this first patch). Love that Coco is playable too. yay!!
I do have some small gripes, but these are mostly personal preference and I'm sure you probably won't have much reason to change them since I'm very nitpicky and it seems like they're by design, but I figure I'll describe a bit anyways.
The first thing I noticed that I'm not really a fan of is that the slide jump is much more akin to Crash 4's slide jump, where your speed pretty much halts entirely once you jump (not sure if this only affects the 2D mode or what...? But I noticed it the most in the bonus stage). I personally think this feels terrible and vastly prefer the classic-style slide jump where you don't get this tremendous loss in speed. On that note, I also am a little sad that this game doesn't have the classic slide-spin-jump tech that Crash 2 and 3 have, but that one is ESPECIALLY a nitpick from me because I just like randomly doing that technique a lot when I replay those games, haha.
Either way, I'm super excited to see where this goes.
