thanks a lot for playing! Not having a checkpoint was intentional to give the challenge to collect all gems in one go, since it's a short game it felt ok to do it. if it was a longer game i would definitely agree with you that the checkpoint is needed. And yes that's a path with no return so it's necessary to collect the gems on the other areas first. Though i agree this is not a good design, just ran out of time to adjust the level.
