Hi! Thanks for your comment!
Ace Angler is made entirely in C, so it does not contain a .PDZ that you may have seen with other games. C games instead contain a pdex.bin file for the Playdate. The other pdex.so file is so it can run on the Linux simulator, which is the platform I develop my games in. However, I would not recommend running the game in the simulator as the accelerometer controls are not very good (it compresses the 3 degrees of rotation into 2 dimensions).
