+ Very cool to have multiple characters that behave differently and can reach different parts of the level,
+ Looks pretty good, though could be either more pixelated or less pixelated, currently it's somewhere in between, looks a bit stretched rather than intentioonal (playing on 1440p screen, might be the reason),
+ Music is nice and relaxing,
- Platforming needs some work, the collisions are not accurate and sometimes it seems like the only way to progress is to use bugs (or some mechanics look and behave like bugs). It has a janky charm to it, but this is what I would work on first - platforming.
Good job, keep going!
