I really like how you control two characters and have to scale them differently to progress! I think maybe the spikes were a little too difficult to get over at times. I also think sound design would have been really nice. Other than that, great job!
As a side note, I noticed the game is made in Godot. I would highly recommend exporting your game to html so it can be played in browser. Its really easy to do in Godot, and people will be much more likely to give your game a try if they don't have to download it.
Again, great job with the game!
