Controls are great nothing to say about it. The dash adaptive range work fine but not for the axe, it's always a full range throw. Also changing range is too sensitive for me, + maybe if possible slowing time when aiming would be great.
For the cloud bug if you have a discord I could share what I see.
For the tier upgrade I find it misleading, i thought it was 1,01^(stages cleared), but even 1+0,01*(stages cleared) is wrong. For example if I can reach t9 on lvl1 that means I beat 9tiers, 0 to 8, if I don't count the boss too, I still have less bonus that what I should. Also beating tierX(10) which is the final doesn't seem to add to the bonus and there is no way to know if you have beaten t10 or not.
When upgrading crafting speed, the time required to craft is not updated for previous orders.
The warrior double sword doesn't add a sword, while ranger extra arrow add 2.
Shop:
Rounding: the round to next integer in shop is bad, I first thought they were buying item for higher that the item price.
When selling expensive items, warrior visit the shop but don't buy anything while normal png bug at the door and disappear almost instantly apart from thief.
Finally, when you sell an item, for example goblin tusk which is 12,5k, when you catch the stealer you earn that amount which is crazy. You should earn the thief purse, like a flat 10-20.
I could share lots of suggestion but I prefered sharing all bugs I found.
Btw, is there a way to donate?
