Show HN: Tiltbump – another game in a single HTML file

Here's a game my kids and I vibe coded, inspired by another game I saw here a couple of days ago.

This one is supposed to be hard, but not hard to understand, and it's cooler on mobile.

This was my first pure vibe-code-and-I'll-never-look-into-the-code experience. I've been developing for more than 40 years, so it's not natural to me. I'm pretty impressed so far.

Feedback is very welcomed.
