hahahah but in all seriousness your concept looks awesome

Hey guys, Name is Edward and I am a 20yo Aussie programmer studying at Quantm college Who taught some pretty good students in the past (founders of halfbrick were quantm students)

Anyways Ive been programming for about 2 years now and have worked from mod to mod, tool to tool, ect ect. Notably recently I have taken part in the SYnergy Dev group and am the programmer for the recently greenlit OBM multiplayer portion. While I learn more about programming i hope to one day join the industry, setup a small buisness maybe and even create our own unique games.

Cool to see this around, peace out :P and yes, the net here sucks :P
