Slime Forest Adventure
To get you started with the basics of Japanese, Slime Forest Adventure is a great beginner’s tool to acquaint you with basic hiragana and katakana, with the former being the basic building blocks of the Japanese language.
The free version of the adventure game will teach you the very basics, though you can pay for the upgraded versions to learn to read more kanji and complex sentences. However, the free version should suffice for casual learners looking to get into the katakana.
Slime Forest Adventure’s gameplay is fairly simple, requiring you to recognize the correct words or characters in order to defeat the enemies onscreen. It’s great for helping you memorize the easier characters as well.
