It seems they have reused a good bunch of last SuperCan stuff :
textures, levels, vegetation , rocks ...
But the result is great indeed laugh

3DGS can do it laugh

(But you'll have to spend lot lot of time writing your own 3D editor frown , impossible for non super programmers or 3D artists)

I Hope to see some demo of totally new level soon ?

Just do It !!
