Is it just me or does it bother you aswell that there are alot of trial/engine-test/demos floating around on the Scirra Arcade?
I feel that if you want to test your concepts out and get peoples opinions then use the "Your Creations" section of the Forums. Posting demos in the arcade kind of removes the purpose of the whole "Your Creations" section.
Also it feels like its unfair to all people who tested their games endlessly for errors, added own music, a whole game concept that works from start to finish, instructions and so on, to then see your creations lost in a mist of demos and trail games.
This are just my personal opinion and i like to hear what other people think about it, no hard feelings
