@bismuthdrummer thank you for downloading, and I am glad you enjoy it! Our first title, KamiCrazy, didn't have the functionality of it remembering the placement of all the components on restarting a level, and based on user feedback, we added it to KAMI RETRO! We actually released KamiCrazy on a few other platforms much later (as a classic release) and I can't remember for sure, but I think we added the component position saving stuff into that too!
If anyone does end up playing through KAMI RETRO, I can point out that there are also 9 golden letters hidden in levels (they will not appear until the level in question has already been completed, maybe even with a gold medal), when you pick up the golden letters they'll appear in the theme select screen. They are only there for a bit of fun, collecting all of them won't do anything fancy, or pay your mortgage etc.! Also, if you set your team up as four bunnies, the collectables will then become Easter eggs! One or two of the additional characters you unlock require a certain number of Easter eggs, which gives an incentive to play as four bunnies for a while!
