I played on Linux with Lutris (Wine). Everything played fine as far as I could tell.
It's been a while since I last played. I don't recall everything exactly, but the game does feel much improved. The level progression is certainly better. The environments, especially the woods, are easier to see in. The map generation and enemy placement feel much more reasonable.
I started by resetting my game so I could play with the updates, and reduce chances of any conflicts from such an old game save. I did a few runs. My last I made it to the Forked Cave/Cavern (I forget the exact name) with my character at level 10. I like the powered up enemies having a clear visual indicator under them. I was lucky enough to have always had enough space to back away and deal with them over a distance, sometimes with a bit of rolling to dodge them. It was one of them that finally got me when it went around and came out where I wasn't expecting it. I did not yet do any of the red portals this time, as I did not feel I'd built up enough for them. I had over 1000 gold from this last run, so with the new upgrades I will probably go through one on my next run.
The bow is my favorite weapon, and I pick the Hunter when possible. Unlocking the option to pick your class from all 3 is among the first things I go for. I remember being rather bad with the melee weapons in the game, so did not try it this time. I used the Cryomancer once. I find them to be a decent secondary option. The Shattering Orb can be handy for hitting enemies hiding behind things. Still, I am best with the bow, so currently that is what I mainly play with. I may try playing more with the other classes for a challenge eventually, but for now I want to see how far I can get, and unlock as much as I can.
I enjoyed playing and look forward to seeing what you have planned for future updates.
