The presentation is really cool overall. The graphics are great and the audio is fitting. The concept is really neat as well and it fits the jam nicely. However, I feel like there are some issues which need to be pointed out.
The game is in serious need of balancing. It takes a little too long to get new stage coaches and it can be a little too tedious between waves. Some sort of indicator of the range of a gun on the stage coach would be very helpful so that you know if you really need to move yet or not. An indicator for the amount of health enemies have left would also help and enable you to prioritise movement a little more.
This might have just been me but I also felt that the tutorial was a little lacking if I'm being honest. Took me a few reads to fully understand it (Tbh, maybe ignore this comment, I'm probably dumb lol).
Regardless though, this was a good entry. For 48 hours, what's here is awesome. Great job none the less
