Wow this game is awesome.
I like the story, especially after seeing that it was dedicated to your dad. That was very heartfelt and I'm sure he'd be very proud of your game.
I like the music and the visuals a lot, just have a few things with the gameplay I'd like to point out: the level feels a little too bumpy, I felt like I was starting to get motion sick lol, it's also a bit long and I feel like it overstays its welcome a little. Also the game doesn't really give you enough incentive to shatter the gates other than "go do it", which for collecting coins feels pretty intuitive but you could try to make them a more engaging mechanic. I wasn't even sure what they were doing till halfway through the level.
But overall tho the game is very fun, I liked it a lot.
