Buh. No thanks.
The instructions give no hints as to what the powerups drop.
Powerups themselves will drop at the VERY RIGHT SIDE of the screen and disappear after half a second.
When the boss appears, you have absolutely no clue as to what his attack will be before it's too late. Some incredibly fast, unpredictable attack catches the player off guard, and they will most assuredly perish over and over again.
After a death, you respawn with full vulnerability. You can easily get caught in a death loop. Should have added some sort of temporary invulnerability, eh?
No pause button, no mute button... no restart button either?
I finally nabbed a powerup that gives spread-shot, and it doesn't even reach across the goddamn screen. How sad.
The difficulty ranges from too easy (move up, then down, holding CTRL) to frustratingly stupid hard (bosses that just appear and blast you away).
Not even a game over sign or anything. You just die from your last life to the intro screen.
Graphics were alright, sound and music was adequate, but gameplay is ridiculous. While the boss(es) are not impossible, the transition is terrible.
Well, at least you tried. Better luck next time.
