Please take this as the constructive critisism that I want it to be... I, of course, want to see you make more games.

But for this one you took a mechanic that many people disliked from old games, namely being forced to walk to a specific place to enable you to collect stuff you have seen a while ago with almost no changes in environment and challenge (see Donkey Kong 64) and combined it with levels that are way to big for the amount of content that they hold and hide paws so I only have a 50% chance of walking there with the right flag position. The level design especially made me walk some paths 4 times (in, shadow paw, out, flag, in, paw, out) turning this game into a walking simulator that the few platformer parts couldn't make interesting.

Also, that last door was overhyped.
