I'm definitely going to look into the AZERTY integration in my next games, thanks a lot for that.
Oh, I get what you meant by the portrait now, yeah I shrunk some of the images a little bit so they could fit in the frame properly. Which I now realise I could've just made the frame bigger, but whatever.
As for the doors, yes while it may be realistic for doors to open one way, it isn't very realistic when they push you behind them and get you stuck for all eternity.
Thanks a lot for the suggestion in graph theory, I'll definitely look into it! The binding of Isaac has still the best procedural generation imo. Sadly I do not speak french, but I intend to learn it at some point!
Conclusion: I am glad you're glad I'm glad (I couldn't resist)
To answer your question, yes the game shows an ending screen after you beat level 3 with some high quality written lore.
