The game has a good concept, however I really think the controls are too hard for it. The character floats on the platforms and the movement being decelerative instead of changing direction immediately makes it really hard to move in a closed space like that. The attack seems to have a cooldown but nothing tells the player when it is finished so it's hard to time your jumping attacks. I can't seem to jump high enough to go back to the upper platforms and I fell off the screen, it would be great to put collision boxes around to prevent that. I think there is a lot to improve, but the initial idea is good, the characters, volcano background, pipes and smoke are all pretty and you are the first one I saw having the idea of putting the balloons as enemies. The game has great potential, good job !
