So I've played it and I figured out why it crashed, It's just the concentration of mines in one place so pretty much too many Technicians in one place that get spooped

As for the level, It was good! Only problem is I think there is too many enemies in one area (This is not just for this level, Your other two too) but with time and effort you can get past it which is good at least, It's doable :D

Thanks a lot for the positive feedback mate! I'm still very new to this and learning, but I appreciate that you enjoy my levels.

Alrighty, Thanks! As for the crashes I think it is just explosions, My computer is actually quite good, it runs multiple things very well so it confuses me why it does crash, It probably isn't to do with your level though but more the game, Either way thanks for the help, I'll play your level to the end and see how good it is (Probably great from how your other levels are)

Getting a whole bunch of reports about crashes and I don't get those despite having a terrible PC, so it's kind of confusing. Turn off gore and turn graphics to low, that should help.

For rafters, hold right then grab a ladder mid-air - the timing isn't easy, but it's certainly do-able, and you can stay at the very first section until it's safe to fall (you don't need to traverse the rafters from one end to the other - the reward at the end is optional).

I wish I could play the level but there seems to be a lot of crashes with explosions and it is extremely hard to move with the rafters (How the hell do you traverse them!?) so I can't really say much else about it :C
