Thanks! I see a large number of crash reports recently that I'm assuming are from your sessions, and they are all patched in the current (soon-to-be-released) version! The Flashbang is working as intended, same with any grenades, that they affect any character, not just hostiles :)
Do you mind if I ask what you don't find visually appealing about the game? Do you enjoy pixel art at all? Other than some minor changes like small animations to give combat environments more life, there won't be any major overhauls to the graphics. But I'm always happy to take criticism into account for future works!
