I do have to agree somewhat that there does seem to be too little payoff. I disagree about it in the beginning since you really don't need that much to start winning. But later, when you maybe have multiple ducks or just need to go back and level up to succeed in the later stages, it begins to feel very redundant. I suggest a couple of options. First, that there be a strategic advantage to buying the more expensive eggs. Either they learn faster or have a higher level threshold (though they would definitely have to find some way to learn faster if the latter). Secondly, showing marked improvement in performance within the minigames. For example, if they have a high level in running, they actually move faster across the board in levels like the first running and climbing boards.
