Cheers for the in-depth reply :) You'll be happy to know we do plan to add the QoL updates to this build as we go so I have added your bugs and suggestions to my list.
1. Open 5 chests as the Sage is the current way, maybe it wasn't updated in the text
2. I'm not totally sure what this is, but if you send me a pic of it I can likely figure it out
3. I'll look into this one soon and fix the framerate dependencies
4. You're totally right, the eyes shouldn't tick down when the game is in any type of pause state, will fix
5. Yeah the Graggle packs are disabled for the time being as we don't have time to make it fun just yet. Graggle kinda works conceptually but it's quite boring until we can dedicate more time to it
I don't see your comment as negative at all, in fact you gave such great detail that the time taken to leave this kind of comment could only mean you care about the game, which I genuinely appreciate!
The animation thing happens late into a run when you sell something and get coins flying in. When that happens, if you have enough lag, the coins can start to orbit around for a while until collected, or they become part of the circle of doom (which is just a ring of coins orbiting in the middle of the inventory), which led to my game requiring a restart every time it happened, as they don't get removed upon clearing/leaving a run. (I don't know the exact trigger for it, but if you were to run a particularly strong build into the late game and sell some items, you can probably encounter it)
