Thanks for referencing the play-through video. I only watched the section which helped me to find the next level-pass.
What a nearly perfect 8 bit game you created. Well done! I played many 8 and 16 bit games (back then in the good old 1980'ies, as well as today).
Do you intend to publish a few more words about the "making of" your game, next to what you wrote in the very very short "dev log"? For example are you a professional programmer or graphic artist, or did you already collect experiences in the 8 bit days, did you use an assembler or a compiler or special software tools to pack all the code and data into the <64 KB RAM, or the like...
No private details needed, just some info to get an idea of what it takes a ~one-man-developer to create such a lovely and polished game.
In any case, all the best to you, and good luck with potential future games.
