Feels really polished for a jam-game, though I did somehow get stuck inside the rightmost wall.
I hope you'll eventually get to adding some goals to the game.
You could throw some tower defence into this: Plant deadly plants to keep the creep at bay, but you have to fight through your own garden in order to upgrade and maintain it.
