Fun game. It works really well as a "coffee break game", and is satisfying to play. I personally thought the level was pretty well tuned to the player movement, with platforms being at the proper height and the dash covering a meaningful distance. I like how enemies not respawning both work as a punishment and "reward", since it makes the next run easier while reducing its score potential.
The only improvement I can suggest is to add a display for the players hi score at the title screen, but that's clearly a very minor point.
Hi score: 14160
Not really related to my impression and ratings for the game, but I once managed to accidentally clip into the ground by dashing into (and getting damaged by) an enemy. See the attached picture.
