It seems it does work on browsers like edge, chrome and firefox. I know there's some issues with other browsers regarding the support of certain javascript API's. A different browser could do the trick.
Even though sometimes the enemies that pop up leave you with very little time to react, I had a lot of fun playing this game! I liked the ending where a time constraint is being added to the already confirmed game mechanics.
Great job on the incremental difficulty and character control, it was a really solid experience. I love the idea of slashing the flag in half to complete a level, nice touch!
