Not commented for a while - it's looking great, love the epic-size of the stages. Just one comment though, it doesn't seem very clear where the next doorway/room entrance is until you walk through it and the ceiling disappears. I can see this leading to alot of "trial and error" for the player, which in turn will be time-consuming and ultimately boring.
Might wanna look into that. Otherwise though, very cool... especially for Red Dwarf fans (like me)!
thanks and noted- i havent done any further progress to this in over a year- I decided to go 3d with it.(I will return to this project sometime because It is still fun to play- to see the 3d version check my website in progress-
