Off the jump the first level feels quite punishing, many fast moving enemies with quite high health bars. There's no indication of how many waves are required to complete the level, I think I reached a third wave before dying. Not being able to pass even the first level without having to watch an ad feels bad. I think there should also be some visual feedback when your own ship gets hit, I can't keep track of my health bar with everything happening on screen.


Edit: I might've just got to wave 4 or 5? Only because that run shelled out some health / shields / whatever yellow is. I'm sorry to say I don't really have any desire to spend more time trying to get past the first level.
