Yes, it could be. Somebody suggested me this C compiler that i did not know. May be i will try to use it. Not sure i will port that game to this compiler , but for a new game for sure.
If you ask me, i think "Donutsman" is worth it. The game itself is good, it only suffers from a bit of slow gameplay and if that could be fixed, by using a faster compiler, it should be done. But of course, that's your decision. It would be a fine thing, though. :)
