Haha yeah, I already ran the "MOM" joke in Poison Heart and in fact I also recently re-used it in map 3 for Blast Radius somewhere, doesn't get old.
Congrats on finishing your map, race against the wall count is always some cold sweat. Had to take a close look at your first screenshot to see whether or not that wall corner was new .art or if you had actually worked out something crazy there, looks cool nonetheless, green brick texture is always a funny one and not the most usual pick for indoors but I really like it, goes well with the beige/brown and the tile itself has this TMNT feel to it. Also that other beige wall texture in general I also tend to really like, always makes for some super moody places, spontaneously seeing that pic I instantly thought of the apartment at the beginning of Gambini's Blown Fuses which to this day is still one of my favorite locations ever created in a user map.
Second screenshot is also looking cool, I love your detailed ventilation systems on the roofs and the terrain work is pretty cool, the location in general has a really specific tone to it and feels like an actual base/prison.
And yeah that's a car wash in map 4, I kind of expected the screenshot would give it away but I wasn't certain so it's cool that you could spot it just from that angle (albeit not the most obscure one). Thanks for the kind words, always good encouragement.
Also, not the screenshot I expected to post, but look at more of my bullshit:
This is a glitch I'm getting in game when exiting one of my elevators, probably due to the complicated line work everywhere (I don't think any really overlap though, I need to check). I don't really mind it because the bottom floor only flashes on screen like this for exactly one frame and there's no HOM nor warping even with the old eDuke32 build I'm using, just the image of it popping up really quickly (it's quite reproducible though - which is the only reason why I could get lucky taking a screenshot). What kind of gets me is those two floors share absolutely zero physical connection (this bottom floor isn't even the one you access the elevator from, it's a different one), they're only linked together by silent teleporters (but are built on the 'correct' coordinates), and are basic SOS (I don't do TROR); I didn't even know Build could really render two zones like this. I guess I've had and seen this type of 'visual clip' in other maps before but here it really looks funky.
