@iivvoo - c'mon mate! lvl23 and you've only just noticed that a lot of the "high" scores are the result of editing files rather than gameplay?
The games fun tho - real good time waster 4/5 - should get more difficult and has a few issues, but still fun.
Got bored after a while - too buggy - had a crawler walk thru my bullets, sneak past the guys with guns'n'saws and "hide" under the RHside window, immune to everything!
Given the first comment I doubt if u can do better :(
"Musics" annoying, plays a bit slow but nice attempt - course, you have to let the ozone die to see what happens ;)
