With the new 1.1.0 release there have been some bug reports and some suggestions. There's some other new features inside the engine that are also worth exploring - so we did that in this patch. CHANGELOG:

• Fixed graphical issue in E1M2 (Thanks Akelaphobia)

• Fixed physics offset for walls and assets (causing invisible collisions with cars at the wrong spots)

• Fixed some performance issues with lighting system

• Fixed headshot effect happening even when friendly fire is disabled (Thanks Akelaphobia)

• Fixed explosive damage ignoring friendly fire (Thanks Akelaphobia)

• Added ability to remove points from lined sprites (use Delete button)
