Small thing for anyone interested to play this
(Was gonna write this on the FA journal but it seems more useful here):
Since the game doesn't seem to have a framelimiter option yet, I used Rivaturner to set it to 60. However You need to pick the right .exe for that, which would be "Momulator-Win64-DebugGame.exe"
(You also need to launch that specific .exe to get the game to run at 60).
