Interesting use of the theme. Definitely a fun way to spin it into a puzzle game. I could definitely see this idea incorporated into a bigger game. However, the controls feel very stiff to me, especially when you're in side-scroller view. it feels off that you can't go up and down(it could be replaced by jump or crawl for exemple). Also, the jump + movement not working at the same time is really frustrating(but I guess that's part of the gameplay lol).
Anyway, good job.
Ps: Not a big deal( except for performance freaks like me), but the game runs terrible on my laptop(i'd says it can handle roblox medium level of graphics). I'd presume it's the reflection on the ground that's costly on gpu resources to emulate. If you guys wanted to improve performance for the potato pcs I'd look into baking the reflection while loading the scene. you can barely see the changes in the reflections since the map is mostly static so it wouldn't change much(also chunk loading per section could help).
