Hi hi, thank you for playing :)
It would be difficult for me to add a 2 player mode actually since it wasn't planned from the beginning. Also, on 8 bit platforms, I'm afraid I won't have CPU time enough to compute this load. I code in C, not in ASM so performances tend to be worse.
I'm aware of the counter clock wise rotation, but it will be added for hypothetical physical releases.
Cheers.
