I really like the game so far, but it's quite buggy. If you clear your data, pretty much nothing gets cleared (achievements, initial rewards), also teh achievement screen should progress somehow, right?
I encountered a bug with the casing. It never registered that I bought Ruby or Diamond casing, even though my robot changed colours in accordance. Thus it was also possible to buy it an infinite (as far as I tested) amount of times. This is the same problem as Devilkiss is trying to get at (see previous comment).
As mentioned before, it doesn't always recognize it when the player press "Enter", which is the biggest flaw. Also, greater variety and difficulty options would be nice! Overall a really cute game :P
I think it's an excellent game. The only real problem has been mentioned before, and it's the black and white performance scale. Why do my boss and team mates hate me because I almost make those more or less impossible shots, only to hit the bar, and if I don't have any randomized shots at scoring but make every pass it's still bad performance in both my team mates and my boss eyes. I reccon it's hard or close to impossible to code but it's what taking the game down a notch. Other than that, excellent work!
The introduction, music and voice acting is quite fabolous. I'm only at level 5, but now I'll be stuck till the end of the game to see how the story develops.
Don't use hint on last difference, last level, or it will "bug out". Last difference is supposed to be most leftmost/righmost building, but ir doesn't change colour correctly when the graphic sequence is activated.
