井底之蛙 A frog in a well

Ready for a hellish challenge? Are you prepared to play the most difficult platformer you've ever seen, and get back up time and time again after countless deaths because you're unwilling to be a frog at the bottom of the well? Try this game!



This is an extremely hard platformer/avoidance game. You'll need to manage the temperature and fuel of your rocket backpack, collect coins to buy upgrades, and traverse seven increasingly brutal terrains: the Scorching Space, Frozen Wasteland, Dark Castle... Ultimately, you'll rise from being a frog at the bottom of the well and reach your own slice of blue sky.

The game’s duration is a mystery, but even after completing it, you can still aim to break your own records and unlock five interesting achievements.

Story Background: In the near future, unscrupulous corporations exploit cheap labor to mine minerals from the asteroid belt. The protagonist, in order to fund his critically ill daughter’s treatment, must venture into mining. However, he and his team encounter unknown monstrous entities on the asteroid, trapping him in his own mental world...
