Description (written by the developer; not a statement by this register)
A tower defense set between broken timelines. Classic, Modern, and Future eras of Roblox have collided into each other, and every side thinks that you're the threat. You're dropped into unstable zones where maps overlap, time loops, and whole eras bleed together as a whole. Protect the timelines. Survive it all. And, try not to wonder too much about what caused all of this. Join our group: "The laboratorium" to gain an extra 150$ starter cash! 🕹️Keybinds: E: Upgrade X: Delete R: Rotate 1-9: Tower

Growth
Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.

Monetization — game passes
Game passes for sale and their prices, measured from the Roblox passes API. Developer products bought inside the game aren’t publicly listable.
Badge funnel
How many players have ever earned each badge — a proxy for how far players get before they stop. Steep drop-offs mark where a game loses people. Win rate is the past-day share of players who earned it; categories are assigned by a language model from each badge’s own name and description.
