the gameplay is simple and really fun. the only part that i thought was a bit confusing was the fact that the bombs have a hitbox that lingers for a while after they explode. it took me a couple games to realize what was happening.
i also think the way the shield works is a bit weird, it disappears after a while of not hitting anything, and the shield is also bigger than your character, which means that a bomb that would not have hitted you, will hit the shield instead. it felt a bit disappointing when that happened, cuz the shield seems to be really valuable to keep the coin multiplier as high as possible.
other than that, the game is really cool, i like how cheery the music is
