The bunny combination idea actually sounds really cool - kind of like alchemy... bnuuy alchemy!!

Though yes, I think laying a very solid mechanic foundation is very important to make the levels more engaging. Void Stranger for instance does some... things, but aside from that it's fairly simple, with the key focus being the staff mechanic and tile manipulation with it. You can pick up a tile, and you can put it over an empty spot. That's it, very simple but offers a lot of room for puzzle design even before introducing any gimmicks, tile types, enemies etc.

Of course, you don't have to go their route. I just think more ways for bunnies to interact with each other and the world would be very fun and engaging to explore. What if the bunnies affected not just 1 tile and then perished, but more? e.g. a fire bunny setting grass tiles on fire after walking, or ice bunny being able to walk over water tiles and turn them to breakable ice? It could go especially well with bunny alchemy, having the player figure out which bunnies they should create (and how) in order to solve a level without running out of bunnies.

I hope the feedback will be helpful, do take it with a grain of salt because as you said, players may have different genre experience going in and I just happened to play videogames too much ^^'

Though I do recommend picking up Void Stranger as it's on sale right now - maybe not necessarily for inspiration but because it's just a very fun puzzle game with a very special atmosphere, lots of twists and depth to the game. And to a fellow bnuny enthusiast, another neat puzzle game I'd recommend looking at is Paquerette Down the Bunburrows - it's not exactly sokoban but close enough I think. Pretty cute and has some clever puzzles. And bunnies. Lots of bunnies.

Cheers, and good luck with Bun Below and future games!
