300MB should be enough in general (except for a weird Intel full screen bug I just discovered).
Can you try the 0.0.10 version and send me the contents of error_log.txt?
okay that was weird. So I downloaded 0.10 and again it crashed moments after opening, and never even created an error_log.txt
but then I closed everything and tried again, and it worked perfectly, it ran really well and everything was fine. I just checked again now and yeah launches fine again, so that is weird.
