From my perspective, this is a great outcome for a game-making attempt. There's no shortage of fun games coming out lately - far more than I have time to play. But these days they're largely made by amateur non-programmer indie devs tooling around in Unity or similar, and have no technical merit despite being very fun. What I'm lacking these days are fun technical accomplishments to read about in the gaming space, like a GBA raycaster.

No offense meant to the author at all, but I probably wouldn't have played this game even if it were fleshed out and finished. Very glad I got to read about some of the technical decisions that went into making it and poke through the code though.
