Neiva is a cute game but, a bit of a hard puzzle solver I think it makes it 10 times more difficult that I tried this on keyboard instead of controller which
I believe the game is intended for.
Sorry that the controls for mouse and keyboard weren't described in the game. The intended controller was by using an Xbox 360 controller. You can change between projectiles with the keys 1, 2 and 3 on the keyboard. We added a description for that now in the text. Thanks for playing anyway! Hope you give it another shot :)
