Yes the A and touch left aren't working on some levels.
It's fixed already in the dev version.
The character jumping constantly is a new one :o

I used Chrome on Mac. I’m not 100% sure how it happened, but I think it happened because I was pressing the UI-buttons and using the keyboard at the same time in window mode (not full-screen mode.) If I press and hold the “up” button in the UI, and drag the mouse outside the window, it happens (I’m not sure if this is what happened when I experienced it the first time.)
