maby paint could be done simalar to creeper
well i mean there are things like the accelerant paste [?] that we cant implement that easy. well we can do the lauch platforms and most of the portal work just well, but the ALL new things in portal 2 are, now, impossible to do, meaning you can only make a bit of the levels. try making addons. they usually work. i LOVE portal so i encourage [?] most portal builds, but new stuff+blockland and stuff=loooong progress and needing help with the addons
