Thanks for allowing us to hit 20 ratings!
We created the game Elos (every 10 seconds -> e10s -> elos) using Unreal Engine during the game jam. I did the main part of the code, a friend created the music, tested the game, and provided valuable feedback during this jam. I had a ton of fun, and will participate in LD52!
It was probably harder to get ratings because of the filesize of the game, but after rating a lot of other games (about 25 or so), a lot of people began providing feedback. Not many people use Unreal Engine in game jams, and I can see why, but I decided to use it because I was not willing to learn Unity, and am still learning Godot.

Enemies spawn every 10 seconds, and will try to kill you. Fend them off and gather coins, and upgrade to kill all the zombies easier. There are 3 levels.
Linux & Windows: https://github.com/appleplectic/Elos/releases/tag/v0.1b-jam (unfortunately Linux is untested).
I ran into a packaging error a few hours before I had to go, and so it is a Development build instead of a Shipping build. This shouldn't cause any problems.
