Honestly not a bad game at all. Good sprite art and animations. I think its downfall though is its clunky controls and the difficulty scaling. Each level is a one-screen mega map where you control two characters by switching between them and using their different abilities to solve puzzles, and each level is completed when you find 10 of that level's special item. It can be a bit tedious sometimes catching one character up to the other since you can't play as both of them at the same time.

As for the difficulty, it's almost like this where the things that you take damage from kinda just appear, at least in the later levels. Some of them, like the frogs jumping out of the water, are easily visible and you can see their trajectory. But then there's also stage hazards that spawn off screen and fall down onto you, even though you can't see where they're coming from, so you have no idea that they're even there until you get hit. In earlier levels, it's fine, and you can usually remember where they are. But in later levels, they become so frequent and mixed in with other hazards like birds and bugs that fly incredibly fast so you get double smacked. It's also important to note that only three of the four playable characters have damaging moves, and of those damaging moves, you only get one per character and they are very limited, so you can't just clear all the enemies and traverse that way. To my knowledge, different enemy types don't have specific pathways or behaviors other than maybe their speed.

But again, not a bad game. It's just weirdly boring for the first 2-3 levels and then gets way hard out of like nowhere.
