Congrats on making your first game and submitting it to this Game Jam in such a short time! :D
The factory and card art style are really neat and the game idea itself is very creative. I love how you took a simple idea and added cool mechanics like the Workbench, Upgrades and also Conditions to restrict the solutions. That really elevated the gameplay and decision-making.
Just an idea that came to my mind regarding the energy bar: Since the setting is a factory and the cards are already placed on conveyor belts, I thought it could be interesting to actively control the conveyor belt left or right to reveal new cards (or empty spaces if they were already taken). Each movement could consume energy instead of it constantly draining, giving you more time to think about bigger combos. Maybe even a conveyor belt flush could be an option (as the current Upgrade).
I’d love to see more of this idea! Keep it up, you did a great job! ;)
