Thank you so much for the feedback!
In order of your bullet points.
1. I was thinking the same thing about moving the slide to a trigger! It makes sliding really annoying. Ill also will include the ability to map the controller buttons so people can have any layout that works for them.
2. I did a little tweaking to this so that you don't collide into the green blocks as much. I think in this particular instance, the level design is the issue and needs to be a little more spaced out which would allow for the mouse look wall jumping to be a little more effective.
3. WASD does currently adjust the slide but it is by a extremely small amount right now. I'll make it a more noticeable amount.
4. This does seem a little weird. Ill try to get the camera lean and the slide better aligned.
Thanks again for playing the demo!
