Hey man, thanks for adding diagonal jumping! This is it, in your version it's actually a easier to achieve the diagonal jump than on real hardware but as soon as I started playing the test build, I felt right at home and the feature I use so often was just there which made the game feel like the real thing. I wish my jump button worked so I could record a video of the diagonal jumping in person, it's a little harder to achieve on real hardware for some reason but it looks the same as it does on your version now and it's the same behavior.
Excellent work
