So, I have noticed one stupid think just after I wasted like 15000 coins. When I buy an upgrade better than the one that is next, I will pay the money for the one I chose but I get the next one. For example, when I have a gold drill and decide to buy a smaragd drill, I pay 1000 bucks and get the sapphire drill. Really annoying. Nice game except for that bug. 3,5/5

Great song, I am going to use it in webgame (and credit you). It has the perfect ratio of darkness and energy I was looking for.

I absolutely loved it. It has very uplifting and 'alive' feel to it. The only downside for me is it doesn't loop well, but I guess I cannot complain about that. I had it looped for like an hour now, and still not sick of it. Fits my webgame perfectly, I will use it for that (available on Kongregate under name "Optimal Racer" in like 2 hours).

I like this. It is fast but not annoying to listen to and leaves space to focus on other things. I am going to use it in my little racing webgame and ofc credit you.
