The need to upgrade everything in every level is tedious and unnecessary. It adds an extra ten minutes to every level because the only winning strategy is to max out everything before sending units.
Great game 5/5, but you should make the "Campaign mode" as part of the minigame list so people like NotATheist won't miss it and think your game sucks.
So much fun until world 5, then the paddle suddenly loses friction and slides all over the place. 5/5 for the first 4 worlds, 1/5 overall because that pissed me off so bad.
Whats the deal with the bullet powerups? They make you shoot faster but the bullets become wiggly and less accurate?
Some ideas:
1. The green enemy that tracks you, has unpredictable movements, and is faster than your ship is too tough
2. Make the weapon powerups more interesting. Ideas - Multishot, backshot, tracking bullets, a automatic but weak turret, solid laser... be creative. Anything but an innaccurate wiggle shot.
3. Bombs should reload on death.
4/5 Awesome game it runs so smooth.
