You joined a game on Roblox called: "Undertale: Last Corridor". You spawned in a lobby, the lobby being the Last Corridor area from Undertale split in two, one side having multiple other characters on the Sans Team, and the other having multiple other characters on the Chara team. You saw other Players walking around, with it being 30 seconds left before a round starts. You can also spot a casino in the distance, that has Hyperdust in it that is working in there. A Slot Machine is next to Hyperdust that can be spun for skins, but since you just joined the game for the first time, you have no spins. You currently have only 0 Wins, so, you can only play as Littletale Sans if you are gonna be on the Sans Team in the next round. Perhaps you could look around? You have barely any time to do so, as, 30 seconds ain't much, but, maybe you can get used to the lobby first, right?
