They do, that's not the issue though. When I press/hold all the keys I still lose. One time the "win" jingle played after I only put out 2 fires, so I tried doing that again and it didn't work.
Aah I see. I have fixed it now, and uploaded it :) it was intended to be pressed instead of holding but there is no reason holding shouldnt work, but it works now. Glad you like it so far, hopefully I can get more playtesters. Still a long way to go tho :))
