The 20th Century RuPaul music was immediately muted but it was cool to play as a rare 1944 steel penny rather than a common copper one.

I was entertained. i was even enraged!

But it's so short, and the polish is really lackluster. if it's assets for a bigger not yet released project, that's cool...

but as a stand alone little doo dad, it's really just a gag, maybe i'm seeing too deep into a unity dump...but i feel like this HAD potential, and went kind of wasted.

WAY too difficult to steer the coin. i like the music. i like the art. the story is cute.

the controls? killed this af.

I love the premise – an obstacle course with a rolling coin throughout the house is great.
However, I think you need to give us a little more control over the coin, especially turning left and right. It feels very stiff, so either I didn't manage to turn in time, or overdid it and the coin fell down.

I don't think I ever managed the pass more than two checkpoints in a row because it was hard to make sharp turns or stay on track once the boost kicked in. Thankfully, the checkpoints realign you, so after the first 90° turn, I only needed to go forward and turn a little between checkpoints. I think the coin should move similarly to a motorbike, just slower (e.g. see here https://youtu.be/CLGnRhsIgDw).

Additional details:
– As for the fountain, shouldn't it have water in it? Also, it's clear the pennies are mapped onto square tiles (or planes), because the textures don't align at the edges.
– Falling on the rug at the beginning makes the coin fall through it. The same with the floor around the fountain.
– You slow down too quickly and the kick from the boost is instant. I don't know how the slowing down is implemented, but in Unity, I'd recommend using 'AnimationCurve' ("[SerializeField] AnimationCurve curve" in code to make it editable from the Inspector). Make a fairly steep, but not instant slope at the beginning (the boost) up to 1 and then go gradually down to zero (slowing down).

Multiply "curve.Evaluate( timeAfterBoost )" with the max speed and you'll have a much smoother speed increase/decrease.
– Everything is fully textured except the walls. Even if they're supposed to be solid-coloured, add a normal map and height map, so it doesn't look as flat and synthetic.

Good luck with further development! :)
