This game is really addictive, I could have ended up playing it for hours (I had to stop myself). Really well done, the gameplay is really fun, the art is great, so is the audio. It was a bit slow (but still fun) at first, until I got the double tile mining upgrade and the mining lazer and then it sped up really fast. now I look at the screenshots and there is even more content that I missed! How did you manage to do all this? Very impressive. You could release this game, even without adding content and polish, and it would still do well. (I fear to imagine what the game would be like if you turned it into a full release :)
