Nice game, nice artwork for what I could see but I give up trying to get ending 4. Will come back another day.
For people reading this I recommend reading all endings before jumping to the final ending (If you figure it out) But to aid as the dev is being cryptic about it all here is what I have so far.
CG 1: Click on one of the girls and mention the couples discount.
Ending 1 - Pick Nothing, just hit Finish (No CGs)
Ending 2 - Pick anything that does not match so just select 1 item in each slot (No CGs)
Ending 3 - Pick the following (No CGs)
Slot 1: Flour, Egg, Sugar, Milk
Slot 2: Default Tray
Slot 3: Chocolate Ganache
Slot 4: Chocolate Cream
Slot 5: Chocolate
Ending 4 (Has CGs) - Need to pick the above (I think) and also one more item for Yellow and Blue dots perhaps two (Section 1 and 5), the item hints are the Blue and Yellow words when talking to them. I am sure I am overlooking something simple with the words being:
Blue word 1: Sticky
Blue word 2: Brown
Blue word 3: Sweet
Yellow word 1: Bark
Yellow word 2: Power
Yellow word 3: Spicy
I know it will simple but with the skip button not working I will take a break for pushing the enter key and come back later. I am going to assume slot 1 does not all Flour, Egg, Sugar, Milk but yep no idea.
