Charming game! I did find it quite difficult to play, half of the times I would click a can it wouldn't get selected, I assumed this is because at first clicking on a newly sent can is locked until it's enlarged but even after figuring that out sometimes my clicks wouldn't be counted. The selection effect on the can could also be a bit more clearer and faster to show.
The idea itself is quite fun, and the game still is fun to play but some issues make it harder to enjoy. Good job on finishing the game and hope you make more :)
