Neat idea, but the game could have been done better. I mean, the "best" upgrades for the two menus (achievements and upgrades) causes them to look considerably worse than before. Green on gray doesn't have enough contrast, so it fails at looking nice, and both the outlines and the text remain poor and scribbly for the entire game. I can't find a sliver of sober graphic design in this basic clicker.
Basically, this game boasts a swell enough concept that is poorly executed.
