Momodora I is the first game in the Momodora series.
This game takes a lot of inspiration from other titles such as Cave Story and Mega Man. It's sort of a love letter to those games. It was also the first game project I completed, so it's very roughly put together and really unpolished. I advise you to play the sequels instead!
The game follows the story of Isadora, an orphaned child who goes into a forbidden land to attempt to ressurect her mother.
It's meant to be challenging like an "arcade" game. I hope you enjoy it!
