Hmm, a bit conflicted on this one! I do like the goofy vibes that this game gives off, the presentation is stylish, and I do think it has a pretty solid foundation for a nice platforming adventure as the levels showcased all of the essentials. On the other hand, though, it felt like all this game had was the bare minimum basic essentials and because of that, it wasn't memorable or interesting in any way apart from its goofiness, which felt like style over substance.
So yeah, right now this feels quite boring and devoid of any sort of interesting hook. It's impressive on a 'my first game' basis, sure, but it just feels like there is such a disparity between its stylish presentation and its lackluster gameplay that I can't help but expect more from this. My play session ended up feeling so repetitive, with every level just a remix of the same stuff and the music droning the same tune, over and over: wasn't necessarily bad, but it wasn't good either, just ok.
For other feedback, I do wish you could hold down when wallsliding to slide down faster, as there were a lot of times where it was tiresome to wait while you slowly go down. Also, sprinting was something that was barely apparent when you pressed the button: maybe it'd be better if it gave you a bit more of a boost like a dash, and either way it'd be nice to have some more pizazz to it, like kicking up some dust, to make the transition more pronounced.
Best of luck on future development! Despite my gripes, I do think it has some decent potential to become great, and I'll look forward to playing it!
