Pixel Game Maker MV, which just entered Early Access on Steam, is developed by KADOKAWA Corporation and published by Active Game Media and Playism. It's software that lets you make your own games, without having to write a single line of code.
It's fast and easy and comes with a lot of resources that let you make side-scrollers as well as top-down adventure games. You can also use original materials, which is pretty cool.
Games that have been made with Pixel Game Maker MV include:
Bike Dash Excite!
Witch & 66 Mushrooms
