Demon Time scales the engine time so everything becomes faster without breaking systems like hunger or fatigue. I think the main issue players are having right now is performance, but even if Demon Time instead granted Haste (which does what you’re suggesting), it still wouldn’t fix the issue. I already tested this by giving myself a large amount of Haste.
I’m starting to think the problem isn’t in the game logic but in something visual, possibly a shader or the nodes themselves. (Those aren't 2d sprites but are actually vector graphics generated with code.)
