This is one of my favorite entries yet. Phenomenal simple execution of the idea. I can for sure see this being a successful puzzle game on mobile or switch.
I LOVE the color palette, UI, and overall art direction, but I think you could abandon the pixel perfect grid snapping. It's a little too jittery and would be nice with smooth rendering. I also somehow fully missed the explanation of growing the leaf branches to keep gaining energy so level 2 took me like 5 tries. Maybe re-introduce the tutorial for that in Level 2 since I was able to complete level 01 without any leaves.
Anyway, great work!
