Yeah you're right many people got stuck on the coin puzzle, that's my fault :'(
About the solution for room number 13, it might really not make a lot of sense but I wanted to fit the loop theme a little more, so when you call room number 1 you get the first phone dialogue of the game ("it seems you're stuck in a loop, etc"), but this time it is YOU who says it, implying YOU were Number 13 all along! Not necessarily a loop but it does connect to the start of the game.
Thanks a lot for playing, and for your input!!
Sure! I use Pixelorama for my art, it's free on itch.io: https://orama-interactive.itch.io/pixelorama
If you'd like something simpler I also used Piskel before this!
Now as for how I made the art, I don't really consider myself to be *good* at art yet, For drawing a lot of things I searched google images for references with things I had trouble drawing (either other pixel art or real life photos), of course you shouldn't copy references as is, I just look at how they do certain details and draw ideas from that to improve the sprite. Now I suggest you follow actual Youtube tutorials or something because most of the time I don't really know what I'm doing when drawing 😭
