I play from android and i must say i got a couple of problem with the design for the mobile platform:
1) Holding on stuff for descriptions
1.1) One has to hold pressed on the skills in order to know what they are, because pressing on them one time makes one buy them. This is also a problem because one has one's own thumb in front of the writings... I'd suggest to make it so that when one presses on them one single time, it makes a button that says "BUY" appear next to the skill description
1.2) Almost same for when one wants to see the description of items or skills or stats from the inventory. The difference is just that one doesnt buy them unwilling by pressung on them just once. It still is a problem having a finger covering the description: i suggest to make it so that the description just stays after pressing once
2) Hide text function
Im not sure if there is a command, a keybind, on computer to hide text and hud, but on mobile there isn't this possibility. I suggest to just put a button on a corner of the scereen to hide text and, when one presses again on the screen, the hud and everything just come back.
If it is a problem to modify only the android version, i think these changes could actually be done to the computer versions without any problems regarding the design. Besides, this is just a suggestion/complain, you guys decide what to do with it. Except for that, you're doing a nice job.
