It's simple and cathartic, which is all a jam needs to be! Biggest presentation issue is the lack of sound design. Even if you can't have music some simple happy little effects for sucking up ghosts and items would've added a lot. I think though that the satisfaction of getting more and more characters and sucking up more and more ghosts can be heightened if your individual clones can die from being hit by a ghost without sucking it. That could create a cool mechanic where it becomes harder and harder to keep everyone alive as you get more clones, but you get much higher scores and suck up more ghosts from keeping more clones alive, creating a feeling of sustaining yourself and growing. But anyway this was fun for the quick little romp it was!
Oh and the ghosts could be a teensy bit more responsive to being sucked up. The items sure were but it always felt like the ghosts were easier to just walk up to rather than suck.
