Thanks for the explanations! Yes, Doggo speeding up when there are no enemies is great! It's nice to get a feel for how many enemies are moving around by seeing the speed, and to know that no time is being needlessly wasted.
Regarding handling inventory items, please make Doggo just drink the potions like before. The good point of the previous version was that there was no interaction other than choosing a stat build strategy on the fly. Equippable items should not have negative stats, also, and Doggo should just equip any with higher total stat points, with luck determining their spawn rate, which can be much lower than currently at the lowest luck. With these changes, inventory management will not be manual, and it will feel as nice and relaxed as before.
By the way, in the previous version, when I got to luck values above about 45, the game started lagging extremely on every new floor generated, until at 50 luck, I let it run overnight and it had remained hung, I'm assuming forever.
