I really like the graphics and style you went with for this project, it really compliments the gameplay concept which is super neat, but, doesn't quite stick the landing imo, it's like on the verge of being really good, but, something is tripping it up, and I think what's missing perhaps is a feeling of flow. The ability to lock the characters down provides the potential for a lot of cool explosive movements, but, needing to switch between characters and press a button to stick or unstick them one by one really stopped that from happening, perhaps each one's "stickability" could be tied to a separate button that could be activated regardless of which one you were currently controlling. Now I, of course, can't say with certainty, but, given the functionality that seems present in the game, I think this could make for some really fun and wild interactions and possibilities.
All in all, it's a solid entry with great presentation, and I think it really does have the potential to be so much fun!
