i'm guessing that most of the testers here have not played the "very positive" reviewed game on steam named "keep on mining"......(sold way over 100k copies at $5) i believe with a little tweeking this game can be as good as that game! really liked your demo and had it wishlisted a few days ago when i see it on steam, keep up the great work and please dont be sidetracked to keeping a few testers happy as many people love this concept of a game!
