I've done Any% All Glitches runs on controller before by mapping the alt key to a controller via joy2key, but now I'm trying to switch to keyboard and the alt glitch won't work in certain situations.

When I'm just standing and pressing alt it works every time and when I'm at full running speed it usually works too, but trying to press alt and a directional key shortly after or at the same time, the game won't freeze. This usually happens standing on a single tile and trying to alt glitch. My other key binds are shift for sprint, z for jump and the arrow keys as directional keys, but I tried different key bindings and still had the same issue. I also tried windowed and fullscreen mode, but nothing worked.

Do other people have this issue or am I the only one? Any help would be appreciated.
