It's a bit hard to fully judge the game since there's a few key issues that affect the gameplay loop.
I was very confused on why I died a lot of the time, despite having a bunch of health I would sometimes just blow up?
You can just go to the central house and instantly get to the upgrade menu regardless of doing deliveries or not it seemed. The upgrade screen is obviously quite unfinished as well.
3D isn't easy to do on a short timeframe so despite those issues it's nice to see what was accomplished!
