Was fun. Nice mechanics. Having to go all the way back to the start after each explosion was a bit annoying. Maybe I was doing something wrong. Good job.
Thank you.
As for respawning back to the start, it's all about balancing between choosing checkpoints, lives, and gems at the item boxes.
Admittedly, perhaps I should have one or two "mandatory" checkpoints.
Anyway, glad you stopped by. :)
