Thanks for your feedback! The game controls were not created with the browser version in mind, so I didn't really think of the shortcut issues until quite late into development T_T, but I did add gamepad support and alternative controls (however, I completely forgot to mention these in the tutorial). Using the shift key is a great idea! I actually can't believe I added three different slide keys, and shift didn't cross my mind at all. As for the wall-jumps issue, this was a frustrating bug I couldn't figure out haha. Once again, thank you for playing and for your in-depth feedback; it helps me to improve, so I really appreciate it! :)
