yea, I actually don't like the planting thing, it's useless. at the start of the jam the idea was that you have to plant different crops to procced the level and enemies would spawn infinitely, so the player has to finish planting while fighting, but for some reason I didn't implement that! maybe I focused too much on the art and game-feel stuff that my brain got turned off!
Anyway, thanks for trying the game out, soo glad you liked it. your game is awesome btw, and it's also 6 MB! (not like those Unity devs!)
