Okay so I will do a decently harsh/realistic review
The game is not fun, its way too slow without any context, story, interesting sounds or music, I also did not understand when do you dimension swap, the description gives little details, now that I think about it it actually looks AI generated
Since you did not use any free assets I will applaud you with that, but it does not look the best. Remember there's nothing wrong with using free assets properly if you cant do art well
But do keep it up, you will get better, best of luck!
