Unfortunately, the file is broken, and it’s not possible to play, which is a shame.
But from reading your description of the game, the concept sounds really fun and challenging. I would have loved to try clearing the room under the time challenge—sounds tense and satisfying, especially if a good particle system was used, cleaning would definitely be extremely gratifying.
Your Easter Egg also seems really creative. Using the colorful space to clean the entire environment sounds like a very intriguing and crazy idea (in the best possible way).
The cover art is also very beautiful—I really like your artistic style. It has a very pleasant, stylized look.
I think that’s all I can assess for now. I hope this doesn’t discourage you from participating in other jams, because mistakes happen, and you’ve probably learned a lot from it, as well as from the time you spent creating your game.
