Nice game, the music and the graphics work quite well together, and is definitely synthwave. The little comicbook-like parts are very well drawn, and the gameplay itself is also well thought through. The movement and the overall gameplay is very smooth, and easy to understand but hard to do it quite well.
The controls are pretty easy, but quite hard to figure out - at least for me it took a while.
I lost two life trying to control with the arrows and then the mouse, I guess there was a description somewhere, but couldn't find it. (it's WASD for the ones, who still didn't find out.) Also, for a game with this good 2d graphics, the browser version is very small, I guess it was made for cell phones, but still, it could be larger.
Overall a very well made game.
