I will have to agree with my man jfkE here, I managed to kill the enemies with the dash, which in itself could be a good idea for an ability, but it took some trial and error and it didn't feel fair since there's really no direction. I managed to find the restart key by pressing R but that's more instinct than properly teaching the player how to do it.
Right-click seems to dash but in the instructions, it says to use it to pick-up the phone, so I don't know what that's all about.
Also, what's the main thing that would separate this game from Hotline Miami? As I said, the dash would be a neat ability to have in a Hotline Miami game, but it won't change this game enough for it to stand out.
Keep working at it, I'm down to play it again once it's a little bit more fleshed out :)
