Wow, this is a really cool game! :)
The gameplay loop is fun and challenging, and the ending is very intriguing...really gets me wondering what will happen next in the story! (if you plan on expanding this)
The soundtrack is groovy and accompanies the gameplay very well!
I still have some critiques tho, mainly the sound of the monkeys being a bit too loud, and the fact of being completely udefended when you don't have the weapon, making bad throws very punishing: maybe there could be a basic attack that cannot deflect projectiles but still does a bit of damage? Also, death is not really communicated (I initially thought there were only 3 levels in the game, but no, it was just me getting repeatedly obliterated by the storm at the end of that level)
Overall, fun experience! As said I don't know if you plan on expanding this, but it has potential! :D
