Very well made game, got a little too invested in it for my own sake.
The gameplay is very engaging, the plant unlocks got me hooked pretty fast, it has a very impressive amount of content for a jam game. My main criticism would be the pacing, because this game is reeealy slow, especially at the beginning. It takes a lot of time to complete a run and to unlock everything it takes literal hours. I only got to unlocking the money generating plant and the eye plant thingy even after more than an hour playing. Also speedup wave button would be a godsend.
The art is very pretty, though the inconsistent pixel sizes can look a bit jarring at times. The music's nice and fitting, though can get repetitive (or I just played for too long lol).
Overall very solid entry, I like it a lot. Congrats!
