Yep, this game is boring and money is useless: you only get to train one duck and the hats are just useful for bug exploit, they extend your hitbox for some games.
For example, on the climbing game with the avalanches, i got hit even when in a cave if i wear the pan because of the handle. On the climbing game with the ladders, you can skip a floor if you have the construction cone because the top of the cone can grab the ladder from the upper level.
Also, the score is meaningless, i would rather have an indication of how many level i'm actually making while i do the minigame.
The requirement for the final boss is just stupid, you should be able to choose a skill you want to upgrade based on which minigame you prefer and still be able to win most of the races whith this skill making up for the others.
I can see there was a lot of good ideas but the game just look like you gave up and just released it with bugs and half implemented features. The concept is good, don't give up.
Where are all the gummies running to? If they really are trying to escape, there should be some of them desperately hitting the doors and begging the gummies who closed it to reopen it just for a few second so they can escape the mad killer. I'd love to see that but maybe i'm just a sadist.
