This was a very interesting mix of the deck management and golfing! I liked that having the "wrong" cards opens up another layer of strategy where ball placement after a shot becomes a puzzle!
I found the final level frustrating, I think it pushes the requirements for directional choice, or lack thereof, too strictly.
I also really wish there was a way to zoom out or see the whole map each course, to better plan the route. The first time through the course the spikes or dead ends can also be frustrating to discover.
The game is best when there are a few extra cards to pick up, but they are the wrong cards for the easy win. It feels awesome to plan a 3 or 4 card play chain with a couple wall bounces thrown in, and then manage to pull it off!
If this gets expanded upon, I would like to see more of those "wrong card solve in two shots or more" moments, and less of the moments where I just didn't have a solution at all (last hole did this almost every time).
I'd like the hole designs to reflect multiple answers as well. The current design is a bit too tight with how close the walls are. If the playable areas were a bit more forgiving for loosely aimed shots, I think the card/puzzle portion of the game would feel a lot better to solve.
Music was great, and graphics worked well too. The way the ball orbits and sinks into the exit was a very satisfying touch. Nice one!
