Nice looking game
I agree with Dvalin though. I stopped playing after my fingers got tired about 20 minutes into the 2nd level. I found myself cursing the game every time more enemies came out rather than the boss that I was waiting to see. And cycling between fingers while tapping the "s" key like a madman got old real fast too. The first level was fine, it had its action and an ending, but anything after that just seemed like I was lost in limbo.
The artwork looked great. I liked how the turrets on the enemy fighters tracked your movements. As well as the thrusters sparking for whatever direction you were going in. Everything moved very fluidly.
The sound was pretty good too. Except every time it looped I thought the level was finally over only to find I had more stuff to shoot at.
I would't really call this a violent game, but well enough for a side scroller.
As for interactivity...this game was on the mark. Everything reacted instantly and there were no bugs in the controls as far as I saw.
The humor...there was one joke that I noticed that got a chuckle out of me,"let's attack them before they uh...attack us, yeah..."
Hah hah nice touch dude.
Overall, I would have to say this was a great attempt at a good game with the minor exceptions I said above. Good job 3/5
