Thankyou so much for the feedback, I’m glad to hear you liked it!
To answer your questions:
1) The game ends when you reach max excitement, which happens at 24 butterflies. We probably could have made this clearer sorry!
2 and 3) Yes there most definitely is a way to fail! The “red butterflies” happen when you let a caterpillar go hungry or feed them 2 x incorrect items in a row, the caterpillars begin to eat your butterflies 😅 It’s pretty difficult to entirely fail, you have to kill ALL of your butterflies, but if you start the game and immediately feed your caterpillars the wrong food, they’ll kill your 2 starting butterflies and you’ll get the lose cutscene. Check it out if you get time, it’s pretty fun 😁
