I'm running at 1280x800. I tried playing in Windowed mode, but I found it was more difficult to see ..
Sorry, my fault. I used non-standard resolution for 16:10 displays. Already fixed with your help. Many thanks!
Blue randomly change it direction
Yeah, I'd suggest changing that.
Your comment is a first displasure with it.
I'm still satisfied with such randoms in arcade game. But I will think about that.
It's not so much getting stuck but a combination of the slow acceleration rate and the large character hitbox for colliding with the walls.
Slowdown and collision issues are results of miss-supported resolution. I hope it will not reproduce with current fix.
