It's an okay game, and it does have some potential. However, the menu not being there during gameplay is going to be a problem. Plus (and this is my opinion), the cube goes at a slow, unexciting pace, making the game boring.
Sigh... it's been a while since this game has bee updated. Seriously though, big kudos to you developer. This game has kept me addicted for 3 years and introduced me to idle and incremental games. Are there any chances of there being an update? I hope so.
