Suggestions for the SPACE key
Suggestion: Press SPACE to roll and dodge. Holding down SPACE is a continuous roll to dodge; Press SPACE twice quickly to run fast (click any button to exit fast running after running, and there is a brake action).
I'm in SSF mode so I don't have to worry about the hassle of RMT and chat teaming. SSF mode, it is difficult to do a good job, it is annoying to fight the BOSS with bad equipment, now after pressing SPACE, holding it is to run fast, and as a result, the last BOSS in the second chapter is always knocked down by the BOSS's electric arrow when running, and then he attacks continuously, and he has never been able to beat it. I later found out that I couldn't hit the electric arrow of the boss with the default speed without running fast.
The previous version had continuous rolling, and I think it's okay to fight the BOSS. Now you have changed the continuous rolling to a fast run. But when running fast, as long as it encounters a monster hit, it will fall and then get up slowly, and it is easy to be defeated by the monster BOSS. The point is that when I played the last boss of Chapter 2, I didn't want to run, but when I pressed SPACE, it was easy to run, and then the boss kept knocking me to the ground, and the BOSS kept hitting me as soon as I fell to the ground......
