Obby: Hell Tower Online
A parkour climb up an 80-stage tower that spirals around a rainbow column: 10 floors of 8 stages, with the top two turned into dark hell floors. Red obstacles, lava tiles and shrinking platforms raise the difficulty on the way up, while a checkpoint on every stage and saved progress keep it fair. Up to 9 players share each online world.
The demo opens in English. Ads and purchases in the demo are simulated; no real payments are made.

Features
- 80 stages across 10 floors of 8 stages each, spiralling around a rainbow column.
- Red means danger: spinning sweepers, spiked rollers, red wedges, walls and bars, plus tiles over lava.
- Rising difficulty: longer jumps and smaller platforms higher up; the top two floors are dark hell floors.
- A checkpoint on every stage. Progress is saved, and a lobby podium takes players straight back to their stage.
- Coins: 5 per stage, 100 for reaching the top.
- The finish brings fireworks, the run time and a personal record, so players climb again to beat it.
- Shared online world for up to 9 players, each in a hoodie of their own color.
- Private world with a friend via a 5-digit code.
- Lobby stands sell a Flying Carpet, a Rainbow Trail and No Ads.
