Hey, I tried out those controls and I think they work well. I've changed them in the updated version. RB as dash actually fixed a bug that had been adding an additional constraint. You now fire just by holding the right stick in the direction you want to shoot, rather than needing to use the right trigger.
Yeah, really better! A last thing: do you have tested it with an Xbox controller? Because with it, the diagonal input radius is too small, so is not possible to jump by walking at full speed.
Here the actual asset in the 1st shot and the fix in the 2nd:
If the issue depends by different controllers, maybe it can be solved by setup a mid way.
