Hm... Well I did finish the house. It shouldn't crash anywhere. But still Titak had to do a lot of work to make it look okay
Of real levels, the one I worked on last is the Amazonean jungle [for my story The Amazonean Idol]. It only has a river, Lara, Jeep, a wild boar and a road. I can send you the project file, but I think you'll need a new wad since I think the one I used is seriously messed up.
I'll pm you
