I'm glad you liked the idea. The jump physics and soft locks are a serious issue in this version of the game and would be a focus if I decide to continue work. I'm actually kind of surprised more people haven't mentioned the viewport size issues. Managing the viewport size in WASAM is one of the rough edges on the relatively immature framework I'm using and would require work upstream to do right. I like the framework though so maybe this is a good excuse to go work on that because it's not the first time it's caused problems for me.
