I just lost 36+ hours of work for my entry in the game jam.
Great.
Welp time to get back to work on a new game. Game title The Lost Ones
I feel dumb for asking but I've been trying to play test on opera gx with html5 but it won't run on it only on chrome and safari. Any suggestions please.
does anyone remember the coding to bump it up from 30 fps to 60 fps?
