Thank you very much that's so encouraging! I'll definitely be adding a "remove plant" simple feature in a quick post jam update for that exact scenario. I've seen it play out a few times so you're not alone! I like preserving that moment of realization but then it's too late haha.
I like your idea for more planet rings! I have had so many ideas during and after this jam. New seed types, more control over each plant and note, and I've even considered new planets nearby that you could hop over to and maybe that one is a drum planet or some such. Thanks for playing and for sharing your ideas! Love to hear them!
