Is it correct that I won't be able to play this on Windows 7?

I assume it has but its always wise to put controller support on the Steam page, especially for driving games.

I know, little sutdio doing little games that end up in 1$ bundles. But look at your catalog, see all that RED. I mean you guys have some alright ideas but you're suppose to LEARN as you go. Don't be a sham penny junk maker. Work on it, tweak it, fix the bugs, watch your feedback and improve your coding. You can BE more than this with a little effort. Makes these games playable , I know you can do it. Least you took the time for a card set....

Do you have a contact email?
