Game is fun but you need to explain commands a bit more, eg, long pressing the jump is possible.
Also I was rug pulled by the 2nd platform, I expected the platform to take me with it as it moved but it surprisingly didn't.
Nothing wrong with that but it does go against industry standard so a tutorial may be warranted.
Visuals are very simple and to some extent you didn't really need a 3d game, 2d would suffice
Good job, hope this advice takes you to the next level
