Hi, I'm Duck. Bloons TD X2 started in November 2020 — as a joke one moment, and then ideas and art started pouring in and suddenly it was real. I still build the game in GameMaker, and along the way I built way too many modding apis and finally landed on the Launcher and Kong Studio together with this site. The devlog is on YouTube.
