  • \$\begingroup\$ There may be several reasons for the difference in size. We don't know how they made their game, so we can't answer this question. \$\endgroup\$ – Vaillancourt Jan 15 '17 at 2:14
  • \$\begingroup\$ Some of the factors are the tech or middleware used (a full-featured engine will tend to create builds that are larger in filesize than something that uses only a handful of libraries), the size & number of assets used (some games achieve a high-quality look through judicious use of small or re-used assets, rather than splurge on content), compression applied, etc. Unity has some build profiling tools you can use to investigate which parts of your game are responsible for the largest contributions to build size, so that can be a useful starting point. \$\endgroup\$ – DMGregory Jan 15 '17 at 2:47
