I'm a bit disappointed you stopped playing before seeing the combat since I worked really hard on it and did some pretty unique things this time, I get that you want to limit the time you spend on each title, but it would have been nice to get some feedback on the battle system especially since most people are finishing the game in under 20 mins.
I think you must have failed the shooting challenge and lost 500 credits in the bet, which is why you couldn't buy anything at the weapon shop. I made it so that if you lose you're stuck with the default shotgun, if you win you can afford the best weapon, or you can ignore the shooting game and just buy the plasma carbine.
A few people have had a hard time seeing the arrow entrance indicators and that's on the top of my list of improvements to make, as well as adding more life to the city as I originally intended before running out of time. You did miss a side quest in one of the back alleys which gives you a secret ending bonus, which might have added a bit to your experience.
I did get some useful feedback from you, so thanks for taking time to check out my entry, although it sucks that you didn't get the full experience to give a proper review.
