I completely forgot the color blindness. Thanks for reminding me this! Actually there is one in my company so I plan to add arrow for them as you said.(I added at the start but then removed because it is not so difficult to understand)
“Fast fall or crouch” is a simple but great idea for the yellow button, and it fits perfectly. Thank you for it~
The AGDQ run is cool and I never thought it could be played in this way, maybe I can get something idea :)
