Heyya, fellow Ijmers! =)
I've just made a web-browser version of my fantasy beat-em-up game called Mannarocks.
It's just an Arena mode, where you can test yourself against most of the enemies presented in game, explore skilltree and become the ultimate champion of the Arena! (sadly, I couldn't port the whole game due to technical reasons)
