As our colleague has already pointed out, the initial feeling of being suddenly overwhelmed is very well achieved. I also like the enemy sprites also, and his slow attack, it combines well with the early phase of the game (when you need to avoid to get stabbed from multiple directions). As a constructive suggestion, I think the game would enjoy very much some music and sfx. And of course a little message when you manage to defeat every enemy---which of course I did :)
It was funny to play, good Jam!!
