This was really cool! I like the presentation, everything is very clear and it's easy to parse everything that's onscreen. All it needs is some SFX/VFX to really take it to the next level! Great job, you got a hell of a lot done!
The later puzzles with the numbered blocks is a pretty clever idea (Although the hitboxes of the blocks themselves seem a bit wonky). I could see you doing a lot of interesting puzzles with that mechanic, if getting the blocks to where they needed to be was part of the puzzle along with figuring out which combination of blocks to use. Really cool idea!
