The game's level design is absolutely brilliant. I loved how it slowly increased in complexity and introduced new concepts that kept me engaged. I literally didn't stop playing until I beat every level as I needed to figure out how to line up and time my shots. I could genuinely see this project turning into a full release, it's so much fun!
One other note, because of the controls and the need to wait as the shot "sinks" into the vortex I had the urge to celebrate the difficult and earned successes by spinning around my vehicle or cannon. It could be fun to implement a fun/simple celebration mechanic into a full release.
In summary, I love my little golf car.
