The game is super interesting. It is enjoyable and feels like it’s almost ready to be released. The art is stylish and has humor—very well done. The main problem for me was that the start of the game is way too intense. There are coins, treasures, dragons, numerous cards with various effects, and the clock ticking… I would say it would work much better to have all these things brought to the table one by one. To get the taste of the appetizer and then move to the main dish. But maybe it would be too much for a weekly jam.
Personally, I would prefer the game to be purely turn-based without a real-time clock, but this is not a big problem.
How the cards react on mouseover is really distracting, and the effect could be more subtle.
Despite the critique, I like the game a lot. Best of luck with it if you would like to develop it further!
