We are Japanese game developer team Hapiwaku Project!
Hapiwaku means "Happy and Excited" in Japanese.
We hope you are so happy and excited through playing IEH!
We are very small team. The developers are only 2 university students.
Most of the art work in the game are drawn by my 13-year-old daughter.
We write the stories behind the development on our website :)
