I can see where the improvements and not from 2 come from, and the hard badge really isn't all that difficult. Still pretty good for being the first game.
The game's great and all, but there should be some sort of "clean up" feature added at the end of each level. The game starts to crawl to a slow once all the guts and dust start piling up.
I think the controls are fine. The only real problem I had with it was the double shot popping up while using the tanks. Otherwise it's a great trip off Space Invaders.
As it's been said, this tower defense game's defined by your maze. It adds a lot of replay value to the game, making it one of the better games you'll find.
This is an awesome shmup. The retro feel, combined with the atmosphere the music and surroundings present, make for an excellent throwback to the shmups of old. The difficulty feels a bit imbalanced at times, if only on the final boss.
Still a great game, though.
