Making a spoopy mini-game! Ideas are accepting!

Hello fellow minecrafters of this very server which I do not know besides most ctfers! I have been working on making a... well, the title says it all. It is simply a game of hide and seek, I will do my best to turn the scare factor to maximum. You may think its gonna be a "ehh" or like "its been done before" or even "It's gonna suck" kind of map, but hopefully it won't be.

Concepts:
- Two teams: The Hyders and the Seeker. (You should know which one is hiding)
- Each team has 4 kits to play with. There can only be one player for each class.
- A total of 5 players can play. (So far)
- Mansion map (May not look the best, because I'm not the best builder, but I am a good command blocker)
- Mansion map is W.I.P.
- Secret passages/secrets in general.
- Eastereggs varying from easy to hard.
- Items: Such as traps, abilities, and weapons.
- Edited cooldowns: When you hit a player, you will have 1-5 seconds of weakness X so players won't die right off the bat. (The cooldowns differ between kits.)
+ More Soon

Gameplay Changes:
- The level number on your exp bar indicates how long you can run for. When you run, your level increases rapidly, stop to gain "stamina" over time. Warning: It may be buggy with multiple players. (I just realized I might have to copy the command blocks, that do this, 4 more times >.<) I almost forgot that different kits have a different limit of how much xp you can gain AND if you get to the max, you will be inflicted with blindness until you lower your level. The blindness goes for the Seeker as well.

Future Plans:
- Customizable kits. (I hate this concept, mainly because I can never stop bringing up ideas)
- Balancing kits.
- Finishing the map.
- Hoping this gamemode could have a chance to be on a server in the next 10 years. (Not this one specifically).

Anywho, I hope this sounds interesting, if you have any ideas for this, then let me know! Thx for reading!!!
More coming soon! (This is only for 1.11 so far)

Autism at its finest. :/
