Very interesting concept, I really wish the puzzles were a bit more complex. The only one that gave me trouble was the 4-monster, 4+1 collectible one (i guess a level counter would have helped here). The game mechanic definitely has potential, but of course very difficult to unlock it in the 3 hours time window. I liked the music, and visuals were cute too. The last puzzle felt like an "experience", as it was rather easy but still felt like it was the relaxing moment after a full day of work. Great work!
