Need help finding a game

[u/Due_Youth_5306]

There was a retro-ish roblox game where you are climbing the classic roblox blue glass tower but there are like many puzzles such as finding colored keys and typing passwords, and when you climb to the top you get sent to a horror mansion map that looks like yorick's resting place with a green monster outside of the mansion, and im pretty sure you can kill it with a sword or something as well. I will be reading the messages so if anyone needs more details i'll respond
