Thanks for the feedback! I will look into that bug, I just tried the web version briefly after uploading and didn't find that one.
About the timer, I will surely look into it. Still haven't decided if the player will have some action over it, but he definitely needs to have at least a hint of the next rolling. About the dodge, I plan on adding a dash movement with invincible frames, the player really is lacking actions. Do you think attacking with the dash would also be neat or should I just leave it to the guns/power ups?
