Nice start to a bullet hell game. The 'stun' on hit preventing you from using the charge is good, and could have been useful to have a recharge after a charge attack to prevent charge spamming. And the controls have a few minor issues (you can't move diagonally because horizontal movement cancels out vertical movement). If you continue working on the game, I might suggest allowing the player to slightly steer the charge attack (to give some counter-play to straight down firing enemies) and have where the charge attack exit the top of the screen determine where the ship teleports back into (to give the player a way to deal with "well, I'm going to teleport back into a nest of bullets"). Overall, good concept and fun prototype. :)
