I played your game a bit. Few notes:
- It seems that game does not capture keyboard and mouse input (tested in Firefox / Windows). Therefore, pressing Left Shift to dash triggers Window’s “Sticky Keys” warning, and right-clicking does not work, so I am unable to finish tutorial
- It seems that sometimes character gets stuck moving in some direction even after I release all the keys
- Tutorial tells about dash and shield cooldown indicators, but the icons on the bottom do not change.
- I think it would be better to pause game to give player time to read tutorial text
I am open to testing more if you fix the problem with controls.
