It is a short game: only 30 mins., but those 30 minutes were saturated: not too overwhelmed nor empty. Just like it needs to be, and game finished just in time. And it is definitely an incremental game. I played web version on my, quite powerful PC and didn't have any issues. Art style is simple, but pleasant. And I like how gameplay evolve with the upgrades. The "drill tail effect" on the ore looks a little bit odd sometimes, especially on the newly spawned cubes, but it's ok, I guess. I gave a game 4 stars out of 5 because it's short. I mean, those 30 mins were good, but it's still only 30 minutes. So, if you'll manage to made this game to last 2 hours (1 hour for the demo at least) without loosing the pace, this will easily become 5 stars.
