You nailed it where my inspiration came from :)
When I was putting ideas together I was thinking how I could merge lost vikings, worms and lemmings with different characters.
Interesting that you mentioned different number of ants. When I designed the mechanics I had in mind to use always 3 ants but then I noticed, once the characters were complete, tha any combination or number could work.
Another game in the future that is more inspired by lemmings but controlling ants could be neat as well 😁
