Really loving this, I do have to say tho, I really really wish there was a bit of time where you could still pick things up after you die, i've had several cases where a cool item dropped right as i was killed and it was just sitting on the screen unable to be gotten :')
Additionally, it would be really nice to have a 'lock' on items in the inventory, so that you could press "Recycle All" but keep a few that you're working towards leveling up.
.... Okay I'm typing all of this as I play and I pressed "Combine All" and it for some reason replaced some of my equipment and complete discarded it??? T_T I had a legendary Feather and Speed Potion and had my attack speed up to over 1000% and now those are gone for some reason. Super glad I'm only like 5% away from finishing the last quest and therefore am almost done playing. orz
Otherwise though it feels really balanced* and satisfying**! i like being able to refund upgrades
(*okay, near the end I ended up with no more green upgrades available but still quite a few blue ones, maybe there could be more increase blue enemy upgrades later on? But it was fairly minimal imo)
(** read: i could level up things via grinding a bit to the point where i felt overpowered but in a good way :D)
