Thanks, yeah maybe a bit to hard for the game jam, but I love the challenge. After playing a while you will get the hang of the distance you can jump, its always further than you think :)
Lots of games in this jam tended to be quite hard, I imagine it's a game design thing. We don't have enough skill, or time, to make a perfectly tuned game. I'm sure mine is not as well designed as I'd hope.
Maybe we should all test our games on our non gamer friends and relatives
