I think it was a really great game with a really great concept. I love the playful feel the characters had, and the overall industrial/sci-fi feel that the environments had. The music (though you didn't choose to be rated on it) was pretty satisfying and the color mechanics and splitting mechanics were pretty unique and innovative. However, there were a couple issues that made the game a little difficult to play. The first was the need to tab to switch characters. With more than 2 characters it got pretty difficult and frustrating to have to cycle through them like that. Perhaps also setting them as number options would 1-4 with a little icon of the slime's current state at the bottom of the screen would help make that a little easier. Secondly, it felt like some of the levels had great puzzles, but some got to the point where you were stuck and had to restart. If there were some way to make it possible for the player to recover from their mistakes (sorry I can't think of a solution of the top of my head), I think this would be great. I think you did a great job overall and I really enjoy the concept (probably why I have so much to say about it). Keep up the great work!
