"Your pet killed you, you deserve it!" Ok '-'
Good game man, it reallys remember Tamagotchi, but this is evil hahah
The game should have instruction inside it, its better to distribute. I had to saw the walkthrough to understand what's my objective.
You really should try to export playable versions of this game, I never used pygame, but it should have a way to export to .exe or web.
Have you tried to developing games in Godot engine? It's a easy engine to understand, with a good documentation and that uses the language GDScript, that is very much similar to python. I recommend you take a look at it, maybe helps you in your young journey.
Congrats for your submission, keep improving.
