Glad that you enjoyed the map, Mars!
I got to say, that's some good criticism. I'll take that into account if I ever make more maps.

Loved this one! I escaped on Day 14 via a Prison Takeover. I was going to go for the Zipline route, but accidentally got an older version of the map. Got stuck in vents. Restarted on a new save file, went for Roof route. Lost 3 Utility keys which took me 2-3 in-game days to get as I forgot that the Toilet Reload Glitch existed, destroying my keys in my toilet after reloading a save. Not wanting to collect keys again, I got lazy and caused a takeover on the same file.
Will definitely play your other work. Only criticism I'd give is to provide a map of the whole prison for all layers. It was annoying doing the takeover the 1st time, to find out I need a screwdriver at the very end meaning I had to spend another day or 2 getting one. Without payphones the player can't get any info on the prison layout or what they may need to escape w/o trial + error, so maps are great helps. Otherwise, would totally recommend. Felt official tbh, however the new tileset helped. Great work

The issue with the ladders has been hopefully fixed. You can find the new version of the map in the Google Drive download link. I also added an instruction on how to update the map via local game files, so make sure to read that. Soon enough I'll be done tweaking and fixing issues with the next, not released yet, custom tileset map.

Thank you for telling me this Fover. Hopefully I'll fix this issue very soon and make a link in the description that redirects you to Google Drive with the fixed version of the map.

One or both of the ladders in the top right cell's roof and vent softlock the player. You oughta move 'em a bit. (I think ladders on going up from lower floors should be one tile below ladders going down from higher floors, or something like that.)

Other than this issue that will unfortunately mean I'll need to use the other escape route, I'm loving this map. The custom tileset is great, and so's the level design and overall concept.

Also, in the Shankton State Pen tileset, which you based your tileset off of, the vertical unchippable wall tile is actually chippable. This means that players could reach that ladder in the north of the map with nothing but the orange key and some plastic forks. This probably isn't that big a deal, but I felt I should mention it anyhoo.
