The game was pretty well polished and the art was pleasing to look at. The gameplay reminded me of the gym with the ice floor in Pokemon Emerald, if you've played it.
If you want to keep the movement speed as you have it now, it would be nice to have a buffer where it saves the player's input if they press a direction before the character is able to move, cause sometimes it felt like my inputs were dropped when in reality I was just pressing the key too early.
I think a cool mechanic you could add would be buttons that activate and deactivate barriers, so you would have to make sure you don't block the other one's path
