Self Defense Simulator
A Roblox experience owned by free will studios.
Description (written by the developer; not a statement by this register)
Self Defense Simulator is a wave-based survival game where you have to go as long as possible against a variety of enemies that come from... the Sombies. Wow. I was inspired by the following Roblox AND Standalone games: World Tower Defense; Brotato; Vampire Survivors; Die of Death; Zombie Attack; Tower Defense Simulator; The Battle Cats; The Battle Bricks; Cyber Arena; Megabonk Waves gradually increase in difficulty even adding new enemies leading up to Wave 10. Update: Completely new aim system, which I realise is just like Brotato's weapons after I coded it. Oh well, I think it looks great.

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.
