Alien World https://www.defold.com/community/projects/57141/
Is a complete game art pack to make a fantastic sci-fi platform metroidvania game in the style of the 16-bit console era. It includes everything you need—from seamless loopable backgrounds, tilable sprites, sci-fi props, some fearful enemies, mysterious NPC’s and of course a Daring Hero.
