The controls vary between different games in this game, so just read the dialogue. "?" is for dialogue and "/" is to restart from your last autosave. "Autosave" is just an illusion in the game, you just go back to the last time it says "saved."
After the Main Glitch's- I mean, Glitcher's recovery, you, Dot, and Glitcher are sent to find a new rogue video game character, Ash, a scrapped character just like Dot, only with horrible intentions. Are you willing to travel through my many 6th grade- I mean Mazer Labs games? Why am I asking, anyway? That's why you're playing...
