First of all, thanks for downloading my hack. It has been in production since the beginning of the year 2020. 
This hack is Very Hard and has many old-school influence from tough SNES games like ActRaiser 2 and Ganbare Goemon 4.

In this demo, there's two save points: Seaside Resort (unlocked since the start) and Setsuma Village. 
When in danger of losing all lives, save your game progress. This hack follows the idea of being oldschool, like old videogames. 
There will be tough moments, sometimes RNG may screw you up, but that's part of experience. 

There's no retry doors or pipes in this hack. 

Pain is part of the experience. Conquer your fears and you shall be rewarded. 

Every stage that has a boss contains an 1-up checkpoint, so don't be discouraged if the bosses are tough.

Second thing, some things are subject to change. The second half of Mechanical Oedo is using a port that may be tweaked in the future.
This hack uses the new AddmusicKFF, because some few songs use the pwm command. And finally, I don't know why, but when the controllable
character hits a block with a normal jump, the coin sound or powerup sound doesn't play. But with a spin jump, it plays just fine.
There's some small sfx issues, but I hope they don't compromise the whole experience.

Third, I've added a lot of quality of life patches to make sure the game is fair.

Lastly, I hope you enjoy this hack. Cheers!
