I'm glad you got all the green gems! Thank you for the kind words. I played around with the idea of checkpoints, but I went with the super forgiving respawn system to be more welcoming to inexperienced players. That was decided early into the level design phase of development.
I'm still considering how lives/health can play a role to make the gameplay more engaging. I'd love to hear your ideas. I'm gonna continue polishing it up a bit post-jam.
