This one's very fun!
I love the mental strain of managing a minigame while trying to aim and fire, a great concept that could very easily be expanded with additional minigames. The inclusion of a shop was a great touch as well, allowing me to employ some defensive strategies to assist as the night went on.
If I had one thing that could be improved, it's the incentive to progress the day. As it is, it's possible to farm for money while the difficulty is low, and ignore the minigames. While this is the optimal strategy for ensuring success, it's much less fun than engaging with the systems that are there actively.
Aesthetically, the nightmares are charming and well designed, and the different UI for minigames contrasts really nicely with the dim background.
Excellent work!
