It's a really cool take on the TD genre! The forking mechanic to sort the fairies is genius. I also really enjoyed the writing.

The others below already pointed it out, there's a number of bugs and need to improve the quality of life features. The main gripes I have: the "redirecting zones" are too big. I think what would allow much needed tighter control over the forking mechanic is a way thinner redirecting zone, or even making it a line. That way if a fairy passes it, there's no ambiguous turning back and most of all no trying to separate stacked fairies.

Also I found that it's due to the arrow signs that fairies just hug walls (maybe?)? I show it in the video I made below (which is a showcase of this Jam's games)

cool jamming i likey bloons

waves seem to take quite a while to show up, upwards of like 3 minutes. no idea if they are gettin stuck on collision or what so i wasnt able to play every stage but still cool. big art is very nice and hud is pretty visible and helpful

uhh the 5 cost towers can miss a lot since the bullets they shoot are slower than the fairies thats it bye

While it feels a bit unpolished (UI is clunky, waves often seemingly failed to start, and I could trap enemies to death at the front by constantly changing directions), there's still plenty I liked here. Portraits are very pretty, music is good, dialogue is fun, and I like the concept of a tower defence game with directable lanes. Tower designs are neat too.

I think the fairy designs are cute and I like the portrait art
