Description: Well here's my map so far, clocking in at 131,068 bytes :) Still have to implement difficulty settings, hide secret lines, think of a name, etc. Despite being E1M2 I ended up with quite a lot of baddies... maybe is too much?

Description: I finally managed to bring myself to finish this, apologies for the long absence. I ran out of kilobytes to finish all the encounters I wanted, so the map can feel a little empty after grabbing the blue key, sorry about that. Personally not very satisfied with this, so I propose to put it as a secret map

File Size: 109 kb
Music: Rival battle theme from Pokemon Heart Gold/Soul Silver
Description: Well, it only took me a million years, but here's the first iteration of my map. I call it "Demons Gone Mad"

Rather short, but sweet. Decided to go with a cool MIDI just in case the map didn't end up looking so great, lol.

Not a great result, I tried to stitch some smaller ideas together and hoped they would just magically work together, which they didn't. Texturing was originally going to be in a kind of zany Tom Hall map style to fit E2 but that wasn't working with the geometry either so it ended up looking bland and E1-ish. Normally I wouldn't post something I wasn't that happy with but since I took the slot so close to the deadline I felt like it was better than posting nothing. All in all building this was pretty exhausting.

Also no secrets because I couldn't think of anything more interesting than humping walls for a random item, I might try to add one with the free kb's I have left when my brain is fresher.

All difficulties are implemented to a degree but I only tested skill 3 and 2 for an hour or so, I'll do another pass on them later.

Feedback appreciated because obviously there isn't a lot of time left to polish up submissions.
