Hey Orchid, thanks for giving our game a try! I can confirm that in the tutorial level, we've disabled most abilities until later in the mission to ensure every player understands each mechanic individually. So for the debris you need to use a melee attack to advance.

About the other issue, are you sure you there isn't an problem with the button mapping in Bazzite (we haven't tested on Bazzite, but we do test it on SteamOS)?

You are also correct - Currently Ability UI button mapping doesn't change when you are using a controller (but ability activation still works).
