I just played it. Cool. That center room (the mount) looked great, and so did some of the passages. I played it in D1X-Rebirth so I didn't get to see all the fancy lighting and stuff. Also, it made me want to install D2.
D1 doesn't have coloured lighting.
Isn't this a D2 or D3 level - to have coloured lighting?
If you want coloured lighting, why didn't you just make a D2 or D3 level instead, why choose D1?
