I like the fast-paced Crazy Taxi-esque energy this game was going for where you race to pick up passengers with reckless abandon, smashing through houses and such, but overall the game felt very flat and undercooked to me, most likely due to its jam nature.
The game just felt really unfinished, especially with a lack of polish and special effects. While some aspects like running over kittens was fun due to the explosion of gibs it produces, the critical aspect of the game, aka picking up passengers, felt really boring due to the lackluster feedback: where's my style rankings, where's my score and time pop-ups, where's funny banter from the passengers, where's the satisfying ding and rattling of the score ticking up, and so on? With a really boring HUD and no feedback from passengers, it just felt like I wasn't making any progress until the game unceremoniously ends without even a 'time over' message or anything to signal it. There wasn't even a end score ranking or high score table to see how well I'm doing and compete with others, making it all feel pointless.
Moving on from that, I also felt like the car movement scheme was pretty boring: the fact that you just move in the direction of whatever arrow key you press immediately instead of having to make turns and build up momentum and such like, you know, a car does, really reduced the amount of fun and skill involved for driving.
First impression of the game was also really odd: there was a weird bug that happened to me where suddenly my speed got all out of whack and merely tapping the movement keys would send me blasting at light speeds knocking over houses and such. It was so fast I couldn't even pick up passengers because I would instantly overshoot their positions. Bizarrely, though, despite me moving so fast, I couldn't run over all of the cats that would swarm me. This luckily didn't happen to me on any of my other runs.
Certainly could be pretty decent, but again, most likely suffered from the jam time limit: kudos getting as much as you did in just three days.
