Sadly the platforming code is anything but smooth here. At least we have coyote time which is a good point for you, but jump feels awkward, like the character loses momentum randomly upon touching things, and it also feels like it lacks the vertical momentum for most jump as you are struggling o make even 2 high clear jump from time to time. Which is very because when the platforms align nicely, the momentum feels okay, but there is something wrong with the core of it.
Graphics wise it looks minimal nothing wrong, nothing crazy. SFX were present, but I dont enjoy the music at all sadly.
Overall would be a cool platforming challange but gets some core things somehow wrong. Tinker a bit with it and then you have a cool core system to build upon.
