'I wanna play online' is a program that can convert an 'I wanna be the guy' fangame into an online playable version.
It is designed to work with most of the engines, but of course this is impossible to cover everything so some games just won't work.
On this website, you can see all the games that are currently being played online with no password.
The project is open source, you can run your own server or contribute here!
