That is great if an expansion really is in the works. Me personally i wasnt hoping so much along the lines of adding explosive but maybe a few new materials and allowing more variables, just some ideas here
MaterialsPaper? could be very light weight and float away when not suspended. The armadillo could break through it very easily while still allowing some stopping power
Wood? Sturdy like rubber but without the dampening effect on the 'dillo, and tension or compression wouldnt have as much of an effect. Could have some kind of nice splintering effect when shattered
Aluminum? Strong like metal sheets but flexible like cloth
Springs? Could be compressed or stretched just as other materials, would allow nicer trigger effects without the hassle
VariablesInstead of forcing the player to painstakingly make large structure likes towers or boxes why not have a tool you can select that allows you to click and drag to stretch out a material to build the structure? Much like in the paint program where you can select a tool to make a box, circle, polygon, etc That may be a bit tough to program though, I dont know much about it
Maybe allow the player to alter the thickness of a material to make strong metal boxes or sturdier cloth for example.
Maybe allow the player to alter the gravity in free build mode as Im sure it would remove the challenge of playing the official levels. Or how about wind in a level or even fans?
Just a few ideas here. I would honestly just be happy to see AR2 be exactly the same as 1 but with new official levels.
Looking forward to this if its true!
