This game desperately needs to be able to shoot continuously by holding the mouse down. That would solve one of its problems, at least, but it's got others. 1/5 stars.
I agree with the other comments: if you are going to make a puzzle with 21 knobs, you should at least provide some clues. I'm stuck there and can't leave, so I guess I'm meant to judge the game on that alone. 1/5 stars.
It doesn't give you any bonus points for combos where you chain together multiple scores together? That's a crime against a good game. Make scoring more complex, please! I want bonus points for every fun little trick I can invent. -1 star. 3/5 stars.
It seems like a pretty fun TD game, but I'm not a big fan of TD games. I like them every once in a while, but the negative comments on this game have caused me to only give it a short try. 3/5 stars.
Mediocre at best. A solid 3 stars. It could learn a lot from Amberial. At the very least this game needs a way to go to the next level from the keyboard.
This game's biggest problem is that it's not always clear which side of the line will be filled. My guess is that it depends upon which side contains the center of the level, but the center of the level isn't marked. No matter what the rule is, it should be in the instruction and it isn't, so -1 star. 2/5 stars.
This is a great game. Above all else, it is clever. It's probably one of the most clever games on this site. Also it is well made and has a nice variety of levels. I'm giving it 4/5. It almost deserves 5/5, but after all it is a puzzle game.
A fun game. The unique control design is what makes it interesting, though level 5 seems impossibly difficult. -1 star for apparent impossibility. 3/5 stars.
It's cute, but there isn't enough to it to make it interesting for long. There's no challenge, you can just collect as much money as you want if you play it safe, and collecting money repairs your ship so even if you put a few dents in it you can keep going forever or until it gets boring.
I get the feeling that the developer has never actually tried playing the game. Not only is it exceptionally cruel to players but also what Frostytrees calls an example of a good strategy is actually a sure way to die in the third wave.
