I don't know why people think this game is great. It's boring, repetitive and very very shallow. If you beat the first zone, you've seen all this developer has to show. Move on, otherwise you're going to waste hours repeating yourself for no real payoff.
While I'm sure there is someone who cares about the nuts and bolts about how games are put together, I am not one of them. I came to a games site to play, not be lectured. I know how to use Google, if I want to learn about making games I'll google it. Completely pointless on this site.
This reminds me of a lot of really awful games I used to play when I was a kid. Games that were not fun to play, but very closely resembled work. This just is not a good game.
The first 9 levels of this game are amazingly fun! I had an absolute blast, the interface is fast and easy, and the battles are extremely exciting. While the infinity mode is kind of interesting, it really should have occaisonal things, like a random big boss every 10 levels or so. I played till about 17 and the repetition is just too much, there is no point in continuing playing. There really needs to be something new to look forward to.
This is a really awful game. High learning curve and not a lot of fun once you figure it out. The worst part is it's nothing more than a knock off of a great space game Dark Orbit.
