Geez, before I even started the game I was already laughing. "Run Scam." Excellent world building and expectation setting right off the bat!
Loved the little touches through out. The ads were a joy to read, so I just sat there for a bit so I could take them all in. Loved the ending, shows how much care went into this game.
I never needed to use the numbers to enter card digits. Did I miss something, or was that cut from the build?
A quick tutorial level in the beginning would probably be a great idea so players have a more clear idea of what the change gravity button does and when to use it. I would recommend some code that recognizes jump release so you can have jump reset so that the character doesn't jump again until I've pressed jump. If I held "W" I would jump every time I hit the ground and in some of the tight spaces I didn't want to jump yet but wasn't quick enough releasing W before landing.
I saw some of your early work on this in the Discord and I was pumped to play it. I thought I'd be able to manipulate the ads to drag them in place to make my own platforms as necessary (which might be a cool addition later, along with a lot of what Ghostbit touched on), but this was a blast too. The ads came in so hectic I had to stay on top of closing them, but not closing ones I needed, so it made for a fun balance. The popup noise got repetitive. Maybe that was the point, but if you just had the one sound vary in pitch each time it could help it seem less repetitive.
Great entry. I had a lot of fun with this.
