I think this one hits the mark. It takes some time before it gets really interesting (and might become too difficult after some point - I have not finished it yet), nonetheless, overall, a nice 2d hardcore platformer with hiding aspects.
Death Fungeon does not look like a lot, graphics are nice, still nothing to call home. The hero is cute, the sound/bgm not so much, the controls are alright could be (a lot) better, but still work, and the stealth aspect (hiding, waiting, evading) asks for some tactics (esp. if you go for all the diamonds) and not just running and jumping. What I really like is the smart level design. It's amazing what wild moves you often have to pull off to complete a scene. If you are willing to put some time into this, it's definitively worth the money: 3/5
