Here's an interesting tumblr post on how both Shovel Knight and They Bleed Pixels add elements of risk and reward to checkpoints. I wasn’t aware of Shovel Knights’ checkpoint destruction for cash system till reading this. Great to see other game devs experimenting with systems that integrate checkpoints and saving into the gameplay in a meaningful way. There’s a lot of unexplored territory there.
By the way, our friend Mathew Kumar who originally suggested the They Bleed Pixels checkpoint system has an upcoming game called Knight & Damsel in the works folks may want to check out. He also designed a particularly devious They Bleed Pixels guest level coming in the next update.
