I uploaded a new build based on a newer version of the game engine. It should have a better support for gamepads. However the problem you're describing seems to be related to (very) low framerate. I hope this new version helps, but I'm not sure how to fix that if it doesn't.
Thanks for checking the game though, tell me how it goes with the new version! 😉
First of all: thank you very much for taking the time to try and address the issue!
I did see a significant improved of walking: my character reacts good to the moving input now. Swinging a sword still produced the same 5-10sec lag as before though, which resulted in finding the enemy quickly, but then not knowing which swings I heard were mine or the opponent's.
I appreciate that you tried to make the game playable for me, but I still don't know what causes the lag or the 1FPS in my case. I'm curious as to other players and whether or not the game works alright for them.
Anyways: 10/10 for the idea of the game and for your interactivity :)
