The game starts just fine, but when it gets to the title screen I can't do anything with the buttons - neither mouse nor keyboard works. Hope this is fixed, because the game looks quite nice.

yes game can support controllers but NO KEYBOARDS?? this has got to be a mistake, someting has to be wrong. shoot-em-ups were played with keyboard since their inception on the PC. there is no way it should be different.

I just passed level 6 but did not get an achievement for that or completing the first boss.

I'd buy it for this, assuming one of the 5 achievements isn't something stupid like some devs do who think their game is the only one on steam. e.g. "2k hours playtime", "10 billion total score", etc. Other than that ... there do seem to be polygons, and they do seem to attack, so ... yeah, well-designed product, no doubt! ;P...

it says to switch with the number keys, right? It wont switch when i try to. Do I have to unlock it or do anything to get it of some sort?
