I have very mixed feelings. In general, I'd say that you have really nice engine / base for roguelike. But PTR as game seems very unpolished. I very like aestethics of PTR, altought using this type of font doesn't works well with non-grid movement due objects collisions. Also, movement is waaaay to slow, and range of object interaction seems to large for me. Font are you using for menuses is great, but I think that currently selected bookmarks (like buy / sell) also could have some sort of background - at first, I tought that bookmark with background is the selected one. Auto-interaction is annoying if there are lots of items next to player. After leaving locations (farm, sanctuary, etc), enter-the-location window shows often - probably due player in farm interaction range. Big black blocks of HP / Mana background doesn't looks well - especially in contrast to really nice semi-transparent player character.
Any tips for combat? Probably I'm doing something wrong, as dwarven barbarian I didn't manage (in ~6 runs) to clear first room in dungeon. Why all characters are slowly shifing towards right during combat?
Btw, info that Download for Windows Desktop ([is for] Windows older than 8.1) is unnecessary, because desktop version works well on my Win10.
