This was fun, I liked the fast pace of the game, its easy to understand and play.
I like the animation when you consume enemies as well. The visuals are well made considering this is a GameJam game.
Personally I would have liked if there is some way to recover health with either an item or after a certain amount of enemies consumed.
Does this Jam game have potential for a full developed game? I would say yes, absolutely, it has the basework for a great game. It does need a lot of polish and content, yes, but the basework is there.
