Sadly practically unplayable on an ultrawide monitor since you have to drag stuff that's super far away, and you didnt allow resizing the window. I couldn't advance the season because the button was somewhere off the screen. When doing a game jam always either make your game with a responsive UI or build it in windowed mode (1920x1080 is according to steam about 60% of the market so it's fairly safe to choose for window size)
The drag mechanic is not great anyway, definitely make that a button press if you work more on this.
The game looked nice enough
