This map is a map for 126.96.36.199 based around the Portal Gun from Valve's Portal. It can be played with 1 to... well, as many people as your server can hold :) (recommended to use TShock or similar for the /i command). It's kinda short (it's my first map) but it's moderately difficult to get the intended solution (but there are bypasses if you can't do it). The map ends with "Speed Gel" that you can play around with. It took me quite a while, so I hope you enjoy it. :)
IMPORTANT: CurseForge will mark this as inactive, and that "it may not work with the latest version of Terraria", but it should work in 188.8.131.52 and any version higher! I will not be updating this map.
