Puzzling.
It is what it is: A quick 5 minute generic shootemup. It's solid, fast paced, does exactly what you intended with it. I liked it enough to play it twice, and I'll probably try again to check out the medals.
I do have a few concerns however.
1 - I'm the second person to remark that for some reason at (what I'm assuming is) the end of the game, the screen fades to white and just stays like that. Nothing else happens, no medal, no 'The End', no ranking. Just... whiteness. I left it like that for several minutes thinking maybe the laptop was lagging up, walked away, got a coke, etc, came back... still white. Really odd. It did the same thing the second time I played through. Same spot.
2 - Someone mentioned getting to some asteroids in another review, but I didn't see a single asteroid in the game, nor was I ever in space. What gives?
3 - There don't seem to be enough enemies or opportunities to get anywhere CLOSE to 6 million points. 2 million is pushing it.
So having said that, 2 & 3 lead me to assume that the white screen has left me unable to play the full game.
4 - The '1000 points or less' medal seems completely insane to me. I mean you get so many points so fast and you shoot automatically. It's hard NOT to hit anything even on accident. It's also hard to get killed because the invincibility after getting hit lasts an extremely long time. How on earth did anyone get this medal? It seems technically impossible to me, but maybe I'm missing something.
I hope you iron out whatever issues the game may have. Either way, I had a pleasant little 5 minutes and it's exactly what it advertises itself as.
