not a bad game but i think you should try smoothing the gameplay out maybe make it possible for you to have a lower jump by just tapping up or space and having a full jump be made by holding it the game is very fun though and i am rating it 4/5 it is a great concept but a bit short.
the bubbles the enemies drop are useless now the only thin they serve as is health while in the other game the bubbles were used for upgrading your ship now you can customize it but maybe you should have to spend bubbles to get new parts.
the game is very boring the enemies arent difficult to beat yet the game takes forever to complete for some reason my save file was erased 2 times already officially turning the medium badge into an endurance badge last time i had 2 arenas left.
