I absolutely loved it! I figured out the answer to the keycode fairly easily, first I tried 1990 and it didn't work - then 666 realizing it was too short. Then noticed the hint about math... so I was like - what about one plus the other?? (it was great).
Anyway, the art is beautiful - the sound design is fantastic - I love the stepping sounds and the clown nose honk when getting hit - the shattering of enemies!! The animation and attacks of the different characters are also perfect. You are amazing and I can't wait to play more games you develop! Thank you!! <3
