This is a fun little strategy loop. I had to restart at one point because I managed to move off screen when the ghost first appeared. I'm not sure how! But once in the game, I found it to be nice and satisfying to plan out my next move. Good use of the resolution too, I think the art works perfectly for 64x64. The shadows behind the sprites really makes it pop. Nice job with the game, I think it is really true to the low-rez spirit. It would have been a great Game Boy game.
Also- I haven't seen a game made with GDevelop before- looking it up, this looks cool!
