Tip: Make sure that ALL exit-enabled pipes, doors, etc. have a screen exit defined, or they'll take you to Level 0, the "endless" bonus game. Unless Start+Select is enabled, the only way out of it is to reset the game.
After playing Sheffy World 2 I decided that I wanted to make a game like that.
As I walked in that direction, I paid tribute to a great streamer, Vitor Perseguine (The Reaper) who plays Sheffy 2 very well.
The Reaper's Shells is a hack with short levels and high difficulty. Complex and fun tricks to perform.
Do I honestly hope that the player has the persistence to beat all the levels and find the secrets that I hid in this hack?
Did you do a double Yump?
And a triple yump? You did?
Thanks to Mura Fernando who helped me with various details and to Vitor Perseguine who tirelessly tested this game. Thanks are also due to the other Testers.
