Very polished submission! Variaty of enemies is unbelievable.
Often enough when having multiple rythmic jumps in a row I felt like jump key press was missed. Also, in a couple of places I felt like platforms are just a bit too far from each other, needing to press jump when you already on the very edge of the platform.
I don't know if it's a rule or not, I'm used to Z - jump, X - attack. Here it is exact opposite, I missed many times until get used to it.
Mechanics are implemented very well: enemies, lianas, and even shooting from lianas. I didn't try water yet, only beated mosqiuto boss and found flower boss for which I just don't feel having enough powerups yet.
Map here would be more than handy, it's almost a must. The world is huge.
Overall, it's fun game, polished and full of action!
