Hey, just got to your game now! And oh man, the puzzle design is really clever. I got stuck on the slime rancher ones for a while, so those were really fun to figure out. I really like how you expanded the simple mechanic of the monsters' movement into really complex puzzles... and I also thought you did a good job of teaching how the AI moved through earlier puzzles, so it was Very Possible to logic out the moves needed to solve the more complex levels.
Just one potential suggestion: I think purple's a good thematic colour, but the game feels a bit saturated to be staring at for a while. I'd suggest maybe toning down the saturation of the walls and floor, and maybe making the movable blocks brighter/more colourful so they stand out a bit more (I almost missed them on the first slime rancher level, since they blended into the square wall shape).
In general, I thought the difficulty curve of the game was pretty reasonable and overall it's a pretty good short game already! I'd love to see what other puzzles you come up with in the future!
the music is also really great btw :o
