This was actually quite fun, I really liked the concept, reminded me of Zelda: Link's Awakening. When you have the Chain Chomp following you for a bit, except with upgradable stats! Was able to collect dozens of each colors stat.
Also the art and music we're well done too! I want a devil doggo keychain :3
Managed to find the secret passage by mistake. I accidently kicked one of the babies into it and was like... What? Where did it go? Aha!
Really nice entry, I enjoyed it quite a bit.
