Oh my god, this game is literally perfect! I can't believe all sound effects, music, art and animation were made from scratch. Also the levels are designed extremely well, with the new mechanics being introduced in a great pace. As someone who made a (somewhat) similar game myself, I am really impressed with the amount of well thought out content. My only suggestion is to make the movement smoother by allowing the player to hold down a button to go in a direction for multiple tiles.
Also I remember playing your (flavedogame) submission to Dani's jam about a year ago. It's really cool that you work together with artists to make even better games now!
