TKG didn't have enough memory allocated for the JVM "java.lang.OutOfMemoryError: Java heap space" as indicated by output_log.txtYou can modify this from the command line parameter when launching LGM, on Windows you can also just edit the command in settings.iniidecommand="java -jar -Xms256m -Xmx1000m"Bump up the -Xmx value.
What exactly do you have it set to sorlok?
java version "1.7.0_65"OpenJDK Runtime Environment (IcedTea 2.5.3) (7u71-2.5.3-0ubuntu0.14.04.1)OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)
Another game you could try get running is Sun and Moon (http://ludumdare.com/compo/ludum-dare-29/?action=preview&uid=3479). I just saw it on Total Biscuit's channel (as it's a steam game now), but it was made for Ludum Dare and has source available. There is some problem with draw_set_font(font) when parsing, but when I comment that line out the game runs. So it only needed one change for compile to work. But nothing but the window and music shows on screen. There is some use of uninitialized variables that might be the problem. Maybe I will get it working when I have the time.
