cartoon_baboon, thank you for your comments.
The issue with the unexpected collision is smt that I thought I had dealt with. I think I'll give it one more shot...
Oh, you're "KARAYANNIS" at the list!
I think there is no "Hall of Fame" in the demo version,though!

After playing the game a bit more, do you think the gameplay is intuitive enough? Would you like it to be more or less complicated?
