Cool game! It's like a tower defense / tile puzzle game. I really enjoy the art, sound design, and atmosphere of it all.
I actually ended up playing through this game twice because I don't think I fully understood the game the first time. I think selecting meeps threw me off a little bit. There's a lot of stuff on screen emphasizing that selecting a meep is seemingly super important. There's this really nice animation that encircles the meep, it shows you the stats at the bottom of the screen, and it tells you that you can change meep selection by clicking or hitting space. All this lead me to believe that there was some important interaction that I wasn't understanding when it came to which meep I had selected. But it turns out that it's just a little bit of extra information that's kinda nice to have but not really core to the gameplay experience. It might just be a me problem, but I would consider de-emphasizing this mechanic somehow. It feels like a bit of a red herring for understanding how the game work.
Also, I think it might be worth it to only use one trap type. There is a bit of variety here and I think it just adds confusion when it trying to understanding all the important components on the screen.
Overall, well done! This is a really cool game.
