Yes after a many months of waiting, I have decided to release Insane.
Download it
Right Here (http://knyttlevels.com/levels/Mystery%20Wolf%20-%20Insane.knytt.bin)
It was released before completion because I cannot say for certain how long it will take to finish the remaining screens- after all it took long enough just to get THIS far ^^;
Each obstacle has been tested and is able to be completed, some are significantly harder than others however. A few are taken from the other games I have made, and been given a touch up to be harder.
The game uses one custom tileset for the sole purpose of displaying what powerups you have for an obstacle. I know the tileset isn't the best work and it may be changed when the full game is completed.
Known bugs:
There are two screens with the same issue- they occur when the player is falling/flying directly in the center and do not obtain a power up. It is impossible to continue and there is no way to save without actually getting the power ups first.
For those wondering. the two keys you can get do nothing at the moment. But grats if you find and get them.
