Great game, the hint on the cartridge was a bit too obvious though. I knew it was a code immediately, but didn't know how to use it or want to cheat the game. Even when I was told that it was a code, I needed to read the solution to know how to use it. I thought it was hexadecimal and needed to be converted into base 6 like the other code. Still, it's a fun and humorous game, and could be made into a full game with more content and multiple endings.
Yup totally agree, it's not ideal. For the game jam, I wanted to make sure it's obvious enough when you are looking for it, even if it meant that it was a little too obvious from the start. Also, it's indeed a little bit awkward to ask players to convert into base 6, then immediately show something that looks like hexa but it's not. Thanks for the feedback, I'm glad you liked it!
