This is really nice, lots of potential here.
I had a lot of trouble with the basic platforming (I’m a gamepad guy, maybe that’s it). Tried to take longer jumps as Jump-Dash-Jump and it seemed like my second jump sometimes just wouldn’t happen.
The zooming in when standing still bugged me a little, at times when I’m at the box, it can put the box’s labels offscreen.
The central mechanic, your blow-a-bubble-gun, absolutely awesome!
