overall pretty good if you like slow idle games, the middle (pybarf-rkcybengvba) is imo well paced, but the start is a bit slow, and some parts feel like a spike in slowness (sbeg10-cbegny), do note that this is as of 0.5, and is probably gonna change with updates. personally, I prefer a shorter more condensed game, but if you want a game that takes a few days to get to the current endgame and like months to actually get a decently fast loop, you can have it alongside your other idle spiral and co.
