Space Evader is the first prototype of a game I’ve created from scratch (a game that has a win/lose condition). Where the player has to evade the lasers shot from an alien mothership (the red thing at the top in the .gif). My main goal was to keep it simple (I always make things complicated, which ends up it not being completed)!
The game is coded in C# in the Unity game engine. You can find a more detailed description of mechanics and gameplay in the Readme for the game, you can also find more silly GameDev ideas of mine at the same place.
