Enemies can also suddenly spawn through Realm Rifts. These Rift Spawns are going to be stronger than the ones wandering around. TBD on the enemies... #screenshotsaturday #godstear #madewithunity

In the quest for accessibility, I'm adding Resurrection Shrines for players on the 'novice' end of the platforming spectrum.

In order to unlock the power of a Shrine, you must collect 3 'Souls' from your dead corpses! (the floating blue orbs)

I did this on my 3DS ^^ #Kirby

A few screenshots of the places you'll cross in the Demo of Blu. You can play it today on #gamejolt !
