Hi, sorry to hear that you are experiencing this bug, unfortunately, it is something I became aware of during some playtests at the end of last week. I think that what is happening is an oversight on my part, that when the character is killed during it's movement, the process for bringing the controls back after moving isn't triggering. As a temporary solution, you should be able to still navigate the cursor (while invisible) to the 'end turn' button in the bottom right corner and click that to return the cursor and continue the game.
My aim is to patch the game the next time I can get in the engine (which may not be until mid September unfortunately) and make sure that this, and other issues are resolved in one sweep.
Thank you so much for playing the game and I hope you are enjoying the experience outside of this issue. I look forward to getting more feedback and don't hesitate to report any more issues (big or small) that you encounter.
