Very creative entry! I like the "the game is broken" aesthetic which subverts your expectations and starts digging into devtools and playtest notes. It works well narratively. I like the idea of reading playtest notes (i.e. someone else's bug report) to try and figure out the bugs you're meant to exploit.
I got stuck though, quite quickly, and I think in a game like this it's very hard to know what's a "bug" (i.e. a designed puzzle you're supposed to solve) and what's an actual bug, that will prevent me from proceeding. For example, I got a gold mine unlocked (after reading hints) and then could not place it adjacent to the gold mine deposit, even after exploring all the way there. I'm not sure if I'm missing something or if that was a bug. It's also frustrating that the first puzzle is clicking around randomly to find an invisible button.
I would suggest it's better to subvert expectations after you've established them a bit more: for example if you could build at least a couple of things "normally" before the developer stuff starts happening.
