Found issues (40 mins of playing):

[hexaae]

• set 75fps (I have a 75Hz g-sync display) but there are annoying random stutterings, very few in-game, but much more in cutscenes
  
• horrible Mouse+Keyboard control: mouse is downgraded to light/powerful hits only and can't move camera view: you have to use IJKL keys, like having a 2nd joypad on the keyboard! Nonsense.
  
• some textures are really old-gen low res (320x200 probably). Needs an HD revamp for the PC. Devs confirmed there'll be a gfx update soon however so this is a questionable point...
  
• some apparently missing sounds climbing the first walls (??)
  
• have had to set Win7 compatibility mode on Win10 x64 14393.576 to workaround crash on startup. Not a big issue, but...
  
  All in all I think this game has good potentials... It's fine, and varied and reminds me a bit of Enslave.... but ATM requires to be refined a lot for the PC.
  Will re-buy in a second moment, after all issues are gone and confirmed by users on the Steam PC version.

Thank you for your suggestion. We are working on a major update currently and will have it released soon.

Has something been improved in 2019?
