I think your game is good, the direction is nice!
There are a few things that could be further developed.
Every single time the character dashes or when he kills an enemy the game glitches and freezes.
Also, the heart's blur is caught off.
The flowers are out of focus. Also the boxes, and trees.
The music glitches after it finishes playing the loop.
I think you're doing great as a game developer, also list the controls in the "Author Comments". Along with some stylized topography and perhaps some PNGs.
Thank you for reading my message, please be the artist you want to be and create art that you would love to see.
