Your menus seem a bit bugged - "Play" works when I press enter, but none of the other buttons do anything.
Gameplay wise, it needs juice! The dash to kill mechanic is really cool to play with - some better effects and a clearer explanation of how it works in game would make it awesome.
For the moving enemies that stop every so often, I'd recommend a way to tell the direction they will move in. Whether that's a telegraph, an icon on their "front", or an animation / ease in before movement would help a lot.
