sorry about the crash! it seems stability is not quite 100% though I have had real difficulty reproducing any crashes on play throughs here... (typcial).
you had pretty much seen it all though, just in case you do want to see the final screens and get the heroes send off- you can follow the same instructions I sent in an earlier post (though you will have to fight MassiveMartia again)
Download and extract files:
Open Settings.ini in Assets folder
change
allowshortcuts=0
to
allowshortcuts=1
save Settings.Ini
start game and press play
Press T 7 times (till you teleport into a room with all the powerups) collect the powerups you want
Press T 4 times (till you teleport to a green room with 2 lasers and 2 red flying drones)
go left and fight the boss...
(or if you really want a quick route through also set allowbosskill=1 and press O (Oh not zero) when Martia appears to take her down to just just one health point, but it's mostly just a walk through the final few rooms from where you got to (with a twist)!
