It would be useful if there was some sort of hotkey for the other actions, but I haven't managed to find it.
The three things that I could see needing hotkeys are:
- The laser you can purchase at the start of a game
- The time slowdown you can purchase at the start of a game
- Jade's charge ability
Are there hotkeys for these actions? It's nearly pointless getting them as it is since I almost always die when I have to stop to activate the ability.
Note: this is for the pc version of the game.
