Fun little game. Good idea.
It would be great if you could make this like "better" with
options to create arena and join. Then let's say map would be parkour for some rewards and with that game would be fun and intense, probably would get players to play it.
If you do this please PM me so we can install this on official server
of new development and gaming portal/forum.
