Great concept and overall polish. Took me a bit to figure out I could go backwards but I'd say that's me being stupid more than anything. I battled with the jump being attached to the up key and would've preferred space, but that's a minor thing.
The only issue I had in-game was bouncing between trunks but couldn't get above the branch because I kept hitting my head.
Overall, I loved this. Simple, focused and obviously well scoped because you got nice gameplay, SFX and VFX, and a menu and title screen. Top work!
