Really enjoyed the demo! The first few levels do a great job of teaching without words, and the last level in particular had me stumped for a good while. Great puzzle design and level design all around.
Some things I noticed with regards to gameplay:
- There's no real way to replay levels. If you enter a level you've already beaten, there's no way to complete it because the key is gone. This isn't a huge issue because there's no real reason to replay levels, I just wanted to replay one of them to make sure I'd properly understood the mechanic it was teaching me.
- Throwing the magnet into a pipe to open a door isn't terribly intuitive. At first I thought I had to jump into the attraction beam while carrying the magnet to go through the pipe myself. Took me a hot second to realize the pipe functioned more like a button for the door than a Mario-style pipe.
Some things I noticed with regards to visuals:
- It wasn't immediately obvious to me that the magnet can pass through the thin platforms. The first time I finished level 2, I thought I had maybe encoutered a bug. It wasn't until I tried to replay level 2 that I realized that was probably an intended mechanic.
- In the hub, the background doesn't scroll at the same speed as the signs / doors, creating an unintended paralax effect.
- In the hub, the doors and signs are on a higher layer than the magnet and the trajectory.
