when i prees start or a it fricking shows me GAME BOY 

NINTENDO the its the start screen whit an hiped up song


Tried it out on the Analogue Pocket and worked great, with no issues at all. Great entry thanks for submitting it. It was a lot of fun and has a ton of potential if you continue to develop. If not, it is a nice bite-sized bit of fun with great music and solid TD gameplay. Would like more towers but even so, it was a good experience. 


This was one of my favorites from the Jam. Lots of potential.


What a cute game! Played it on my Miyoo mini. Hoping to see more towers and enemy types in the future.

Same! Played it on my Miyoo Mini too and also hope for future updates! Amazing game!
