Hey! I tried your game and I really liked it. But there are some things that could be improved easily.
My main problem was that in the beginning, the game feels really slow — there aren’t many enemies or elements, so for about 7 minutes it’s mostly just running in circles.
Only after that can you experience the real game — it becomes really intense, and you have to dodge everything while trying to figure out how to craft the different potions :)
You can overcome this issue easily if you start with some shooting enemies and increase the spawn rate of the elements.
One more thing: there was a bit of a color cavalcade, so I recommend using the same color palette for the menu and the game.
In addition, the intro looks damn good — and so does the main menu!
