Very fun and polished entry, I had a lot of fun with this and I am very proud to say I got all the hats and finished the game. That last level almost got me to give up but I kept getting sooo close. Finally got it and it felt great. Very nice challenge loop, feels rewarding to complete the tougher levels. The quick-reset of the levels helps keep the player engaged (we call it the Hotline: Miami strategy), great implementation here to make a very fluid and fun (and challenging!) experience. Love the artwork and the sprite for our little alchemist. The only critical error in this is that you unlock the GOAT hat right away. Cowboy hat for life.
Congrats on a great entry!
