Very cool game!!!
The gameplay is nice and addictive. The movement is very responsive, and this is great since the game sometimes require quick responses.
I liked the obstacles, they are very challenging and diffrent to each other.
The graphics are good. I liked a lot the particles used, they give a good sensation for the game.
The music is nice, it suited very well with the game. Also, I liked a lot the SFX, using your voice to create them was very creative.
I only felt very injusticed with the cannon obstacle. Sometimes I was climbing and I've got hit by it without seeing it. My suggestion would be to make the timer of the fire starting only when it gets on screen.
Other suggestion would be to increase the camera vision at the top, since the focus is on climbing to the top.
Also, I found a bug when clearing the stage and the lava getting me when stuck in the hole, I've ended up loosing after it.
But it's a really nice game! I've had a lot of fun with it! It seems that will fit nicelly in mobile games, with upgrades and etc..
Congratulations for the game!!
