Thanks for trying the game out.
Yes, those lines are a visual bug that happens with nvidia gpu as far as I know. I do not see them in my own setup. I will get a computer that can reproduce this bug soon to fix this issue. Which gpu does your computer use?
I am glad you like the moving platform. I will have to prioritize stage design.
I consider this game to be closer to a 3D Super Smash Bros. 64 clone rather than Tekken. I will have to work on making the game easier to understand and more fun to play.
