Haha... pretty cool. A top down, 2D shooter based around the idea of a virus inside a body. A rather niche way to fit into the Ludum Dare theme. It is a pretty solid game and a decent addition to the game jam. It has waves, increasingly harder enemies, and you are slowly upgrading by collecting the goo of your fallen foes. It does have some similarities with how real life cells work. While it's a pretty good game, it kind of has limited features, considering that this genre has been used many times before. There are many additions that could be implemented: power-ups, skill tree, boss waves plus a few UI things like a menu, achievements system and even a high-score leaderboard. I've featured this game as the second one in my Ludum Dare let's play video: https://youtu.be/_OkbbV2kKUI . Still I do think it's a solid game and if you can you should make a more "extensive" version of it. Good luck and keep it up.
