You are correct, as you can see by the "submitted 15 seconds before deadline" we didn't have enough time to fix these issues and some minigames are non-functionnal. This also was our first game-jam so we didn't get the time managment quite right. We did some quick fixes and reuploaded the game (not finished but somehow more "functionnal") to share with our friends. If you are curious as to what it looks like it's here: https://wendrul.itch.io/penguins-fixed. Another thing to note is that full-screen breaks the game.
Thanks for the feedback! It is greatly appreciated. With the experience we built during this jam I'm sure we will do a much better job next time!
