The Total Problems
The power-up items are almost not coming out during the playing. Even when it happens to come out, the effect ends in only 5s!
Don’t we have to find a way to live at the fight with boss? It's easy mode, but missiles are flying toooo fast or laser-scanning all areas before get out(ex 45stage 55stage)
so where do you want me to avoid it?
And many bugs Including the unfinished units system!
The conclusion is that it's better not to play this game because it's stopped update already!!
