One thing I hate about all idle maps, apart from idle4life, is that people can push you out of to room and mess up your stats. Seriously, this even happens on the NE idle server, knock it off guys.
Solution: Make a step *up* at the exit so you cant be pushed out of the "death area". (Do this also on the tracks with the cow-train)
Another problem is medics healing you forever, also messing your stats up.
Solution: Make a moving floor, that pushes you off a cliff into a death pit.
Boxing ring is a bit small. And layout is a bit messy/all over the place. It's an idle map, so just keep things simple.
Also, I keep getting the purple checkboard bug on the glass cabinets of hats, and the hats at the top are hard to see. Don't use glass and move them all to eye-level.
EDIT:
Also, maybe change the name and put the NE on the end. When I search for an idle server to go on, I type "achievement_idle*" in the search box to avoid results of non-idle maps showing up. So yours wouldn't show up for people who also do this.
