Wow, this is really cool!! I don't think I've seen any game jam games made in this framework, and you pulled it off pretty well! Firstly, I gotta say that I love the music - I feel like it works really well with the liminal feeling of the game. I also really enjoyed how the only controls were with the mouse - if you instead made it mouse to select and WASD/Arrow Keys to move, I think it would've felt disconnected, so great decision on that part! With some updated animations to the UI and game sprites, I really think this could be brought further into a full release :D I can certainly see how the puzzles could be expanded to make them more difficult/engaging, and I see you have plans to work on the game more, so I'll definitely be following your progress - great entry!
