Nice tutorial for people who don't know how to make vanish trails.Other wise terrible.
I can appreciate where you were going with this, but without the knowledge needed to enjoy it, it's useless. Maybe apply this idea to a game you develop in the future.
Don't let me discourage you from creating, but just don't leave the programming to the player.
i made one game with this, its called "neon rings".
this tutorial is for help programmers, its really not a game or anything related.
but i hope others programmers apply this idea on games they develop in the future : )
Good song and quite informative with understandable instructions. Your English is fine, not too bad- but this isn't a game. I still give it a 3.5 for being well constructed, though. Thank you for the tutorial!
