I like this concept a lot, I'm a big fan of the little quality of life stuff like swapping a tile last-second while a blob of icecream is on it to quickly flick it over the other way, and the fast forward button is a welcome addition. I think maybe the difficulty could ramp up a little more (or a little quicker, if there's difficulty ramping I missed), since the gameplay loop does get a bit stale once you've got the motions down for setting icecream in motion. In spite of that I think this is a pretty creative way to approach this kind of game & this feels fun to play in short bursts.
