That is addictive. From the name, to the song and the "CHAIN" effect.
I love what you did here. Reminds me of the early 2000's when we had a wave of games carrying this colorful and full-of-joy vibe. I specially feel that in the soundtrack.
I don't know if it would distract the player, but part of me wishes the witch's portrait would animate when we do a "CHAIN" and during "Game Over". Something simple would do, like facial expressions and a small change in angle. Just a thought, though. This game feels complete already.
