Meh. Could work way better.
Bullet-hell ennemy isnt much fun.
Manual targetting system is one of the worst control sheme i have seen so far in a game. Quite franlky i dont see the point of it.
The ennemy adapt, now that's an interesting mechanic.. but it seems to just add more part where we kill them the most. Makes sense in a way, but im pretty sure all endgames look the same; the boss being huge everywhere and bullets fill the screen.
Maybe having a bigger "play" area, the ennemy could use a bit more of its mobility to point its deadllier weapons at us. It would also give us some extra room to see the bullets coming in.
The time limit is really frustrating. The game gets more challenging on its own as time goes by, let me PLAY dont stop/kill me for an arbitrary reason!
The upgrade "page" should require that we stop to look at it, i saw it for a split second (i was just mashing button and it disapeared in an instant, without warning)
