It took about an hour I think? maybe a bit more or less, can't exactly remember xD I think Hull Bomb and Dash are both my preferred powerup, depending on the current Hull size. At low hull, Bomb is good because it can destroy the bullets close to your ship, even with the glitch. Without the glitch, it would definitely be the best in every situation, because it temporarily increases your movement range. When you have more hull, I preferred using dash, as re-positioning is tough when the circle moves so slowly. Yeah I'm not sure if you are allowed to upload a new version to the gamejam, but I do think the game is worth polishing up if you guys have time- the amount of strategy needed in this shooter is quite refreshing.
