Well, your mechanics are fine, but your graphics and gameplay variety is very poor. Ok start, just needs some interesting content and more work on the graphics.
Interesting game. Lots of potential for sequels here. Similar theme and design to some other games, but some innovation at the edges. Very promising. Could use a little more intuitive UI as I find myself looking for the right text buttons for things half of the time. Otherwise, it is fun. 3/5
Congrats, you managed to make a 2D shooter boring and repetitive. You have to try to do that in most shooters since it's too easy to change things up in 2D. Shame on you. Nice art in some areas, though the artwork is a little flat and amateurish. Overall, nice job getting that much art into this game. But I have to agree with everyone else that 1.) missions are boring, and 2.) miss chance for a shooter is broken mechanics. 3/5
Tired topic. Lame understanding of anything computer related. 0/5 fail for that. Simplistic gameplay: 1/5 for that. Gameplay balance is non-existent. It went from gees, this is boring easy to exceedingly annoying with the 1st large cube stage. 1/5 for that. Polish on the game is minimal. Sound and music is great, 5/5. Overall about 2/5.
Arrows for movement would be better, and movement is too big of a change when just tapping a key. That makes it annoying to pick up gears. Movement really needs to be refined. Just not fun without precise, smooth movement. 3/5
Decent differences game, though a bit short, still enjoyable and cool sound track (even if just one). 4/5. I scored 935 on my time through it, though not worth playing more than once. I started again to check and sure enough, it's random each time. A good sign of quality for a differences game. Page flips and artwork are a bonus.
