Haha seed go BRRR
A very cool idea, I love the idea of a tower defense where you are a lil mushroom man placing down plants. Definitely could use some UI changes though, it took me a while to understand the decay mechanic with the timer, and the controls obviously could use some improvement, but I understand from the other comments that you ran out of time. I hope you make a post-jam version, because I think there's potential here, and I love the pixel art!
