One of my favorite entries so far.
HTML5 build ran badly, Windows build is much better.
At first I didn't know how to build, until I watched your video and tried again. The turrets were easy to use, but it wasn't clear how to best use other items or even what the cauldron, for example, did.
It took a few shots to kill the enemies, but they kill me in one hit? That was frustrating. They could have had some variety in attack or speed, the streams of them were kind of monotonous after a while.
Still, over all, great work!
