The principle is simple, you are a Bug Finder and you are thrown in a standard SuperMarioBros-like randomly bugged (each new game comes with differents bugs) and you need to interact with as much things as possibles to note where there are bugs.
Once you are dead, you will have to send your analyse to developer and you will get a result depending on if you saw the bugs and did not invent ones (indeed the result will always be 3/6 due to the lack of time).
A 1.2 level would be another ''well-known-game-like" (tetris, minecraft, zelda, ...) where other bugs are inserted and so on.
This was my first jam and I was alone on this one from scratch and I finish it at 3am ahaha : 1st day on the ideas as I did not have the opportunity to code. 2nd day coding some hours and drawing assets. 3rd day rushing code, music and finally publishing the game !
