Finished the main campaign.
The game has a neat idea and after getting the gist of it I could advance through the main campaign without much issue. Some solutions are tricky and entertaining to find. The input/output system of the cards was very understandable and felt natural.
It took me a while to realize how important the clock is and that it had a resource associated with it. Also the fact that it could be used multiple times flew over my head initially, I guess I wasn't putting much thought into my actions while following instructions. I believe the clock resource should be separated from the others since it is that much more important.
I don't understand why the number of cards in your hand has to appear with the other resources. The board space management is a bit weird, there is a huge bottom space for you hand, a tiny space for played cards and an even smaller one for upcoming cards. Why are some cards labeled as "start in your hand" when your hand is predetermined by each puzzle? It also limits the kind of puzzles you can make without much gain.
I tried the challenges a bit, but they felt too overwhelming to me. Too many resources to manage, multiple cards to draw and lots of cards with seemingly random effects. And since pocket researcher requires another to be discarded for the rest of the puzzle, it made things extra difficult. I couldn't complete any of the challenges.
I had fun playing through the game, I hope you will be able to work on it further!
