Thank you for your nice comments, it is a long way off from perfection though! There has been considerable work taking place to WB since alpha 0.3, including bug fixes. Once the amigamejam is over (approximately 3 weeks from now) I will update the demo to include options for 1 button controllers (up to jump). Apologies for not having this in from the start! Hope you will enjoy the latest version when it arrives.
