Here’s the current version of Fix (which is still a placeholder title). Move and jump/double jump with WASD or the Arrow Keys. Click/hold to blow smoke, or click/hold/release with the correct timing (roughly a third of a second) to blow one big smoke ring. For funsies, you can also shift-click to spawn wandering NPCs.
PRESS S OR THE DOWN ARROW TO ADVANCE THROUGH DIALOGUE.
Hit switches with big smoke rings to activate them. Note that Jack will only go to the places he’s talking about if he can find a clear path to them (so to get from the bottom floor to the middle floor, for instance, both doors on the bottom need to be open).
