All games are open source now! I pointed opus 5.5 at terraria last night and I woke up with a fully working reverse engineered version of terraria! Added homing missile launcher, tactical nuke and bunch of new mobs (sprites + sound effects done with the @fal cli/mcp) We are truly in a new era of creativity, this is genuinely insane!
