Well Barcode powered RPG wasn't on my bingosheet.
Seriously, every time I think I've found the entry with the most unique mechanic in this Jam, I find another one. I think Reality Code Jumper takes that prize however. I will say if you live outside of the US, where you don't really see UPC barcodes, you can use ISPN barcodes on books though it can be a bit tricky as you do need to skip the first number (alternatively you can just use a UPC barcode generator or rolling a D10 but that's not as fun).
Everything else is simple and straightforward, which makes it excellent for oneshots which is good for a one page rpg. I... can't really think of much else to comment on here. I'm still processing the fact that you've managed to make an adventure generator which uses barcodes.
