This is a very strong game conceptually, the clay pot turning from new clay to fired clay after "death" is a REALLY good visual signal, it makes the "dead" pots blend in with the enviroment, and also makes perfect sense for the theme.
The only gripes i really have with the game is that the jump you have is barely able to get on top of the old pots, and that theres no way to destroy pots that are in the way. Maybe your pot could do a ground slam? that way you could maybe also fill up gaps with pottery shards? idk.
