Day 1
I decided to use Unity as the engine to power my game because it supports the programming languages I'm already familiar with and it's fairly easy to use. I started off with level design and I also acquired some level design props from Unity store. The game takes place in space where you as the player have to fight zombies and collect items in order to progress to the next level. The screenshot below shows where I'm at the moment with the creation of the game. It is unclear at this stage how many levels the game will have but it should have at least 5. I added a space looking skybox, props and lighting to the scene.
