The controls feel bugged as maintaing the click on a direction, the balloons stop after a few seconds going there which is weird and make the projectiles hard to dodge. It took me some time to understand that I could upgrade by clicking on the squares but it would be cool to have the price displayed. I didn't understand how to unlock the other characters. Finally it seems like the start button doesn't work if you click on the upper part. However the idea is cool and choosing the balloon you want to play as is cool. The music is great, the visuals too and I had fun dodging the projectiles at the last seconds. Great job !
