Quite the puzzle concept system, but I am curious as to why it is called 'marble up', when it is about slimes? I did find it a bit tricky to balance out health while attacking slimes in the hopes of surviving.

Really fun entry, would be cool to see more levels. lvl 3 could have been swapped with the last one though

I completed the game eventually, mostly struggled on the same stage, I think it was the 4th (or 3rd) one, the last one I think I beat the first time.

The game is snappy, boosted by its sound effects, and proposes the kind of unique gameplay loop one could definitely have found on an NES cartridge. I had a lot of fun apprehending the different levels, it was satisfying to eventually beat the one I struggled with quite a bit. Great work!

Cool Idea. The difficulty ramps up really high on stage 4 though. I played through at least a dozen times and don't think I made it half way. really like the premise though

Pretty neat puzzle idea! I like it and it's nice how it works. However the pacing is a bit slow. I'd also love to spice up the variety with maybe stage hazards at the same time or something but it's good. My last note would be this feels more like SNES then NES in a number of ways. But it's pretty fun and has great potential.

Interesting puzzle game! I unfortunately just finished a game jam, and I'm too tired to strategize haha
