I didn't buy it on sale now, I had both Sundered and Jotun in my backlog from long ago. Tonight I finally began playing them. Jotun is awesome, but Sundered really takes the cake.
It's basically Super Metroid Lovecraft. I mean, Metroid always had a sinister side to it, in it's deep organic settings and places like Norfair - I don't think it's too far from Lovecraft. I think they nailed Metroid looks (organic+machinery) and level design.
The fast-paced melee combat is as awesome as that of Dead Cells or Dust an Elysian Tale - artwork for backgrounds is as beautiful as the latter.
Is it really rogue-lite, though? I started on difficult and found it way bewildering so after an hour or so started other save and the map overall major layout is still there, though not sure about the small cells between each major place. If it is randomly generated, they did a good choice because the overarching structure is the same and the intent of game designers is there, while still keeping it fresh each time you go through small segments...
What I found strange is that there no enemies restricted to certain spots - they seem to just show up in waves from time to time to challenge you, though they may be tougher in some specific areas.
I'm not really a fan of unlocking skilltrees with in-game currency, which is a staple of modern game design and rogue-likes - because levels are procedurally generated, there's not really many chances or uses to find treasures or powerups in carefully thought-out parts. But like I said, there's an overarching level design in place here and so you really do find some powerups only in specific places - this is an excellent mashup of genres, like Dead Cells being Metroidvania+rogue-lite+infinite runner
All in all, Sundered is a truly excellent game.
