Don't think I will EVER 'finish' this game down to sheer lack of skill but holy heck what a joy ride. Truly satisfying discovering mechanics and unique interactions and feeling yourself 'get better' all the time. Has its share of cheap deaths and frustrating stretches, but really what game with this kind of procedural generation doesn't? Worth mentioning that the multiplayer co-op has been fantastic for connecting with family members that I can't see but I understand that many people still don't have access to this feature on PC which is really sad! Here's hoping it won't be too much longer. Co-op does make the game easier in some aspects but comes with its own caveats that makes it almost as dangerous as any solo run.

EDIT:
Edited to reflect the fact that as of (23/03/2021) I have actually "finished" the game solo. It's one of the hardest video game accomplishments I've made by a long shot - it did definitely feel like some runs were just terrible luck at work - but when the platforming really clicks and you get into the flow of the game it's pure magic. I've played maybe 70-80 hours in co-op and another 20-30 solo and I can see either having their own advantage but there's much to say about this game as a communal experience. Much of my progress was made in the company of friends, sharing what we'd discovered with each other or playing online in co-op and figuring out new worlds together and I think the deliberately opaque details of much of Spelunky really lends itself to that kind of discussion. An experience to treasure if you've got people around you who will enjoy it with you.

Spelunky was a weird one for me, as someone who hadn't played a more classic roguelike, i had previously watched a lot of it on twitch and played my first roguelikes in Hades and Spire before deciding to pick it up.
The thing is, Spelunky 2 gameplay is great, the platforming here is impressive and rewards good play, you are constantly having to jump and use the space to your advantage, so in that way, was a nice fit.
But, this is still a rogulike, so if you die you will restart from the beginning, and that would be fine, however the first area is really hard, like the hardest in any game i've ever seen, and is not just "fair stuff", you can die for a million reasons, the rate of which the death was your fault is like 50/50.
With that in mind, is hard to move on in the game without going well at the beginning, you ended up without itens and dying again, so that is kinda frustating.
i'm shelving this, i made it through first boss and to stage 4, but i've had enough of going throw those moles and sandshrews again and again, for now, i'll say it's great gameplay, but is realy hard, so it's up to you to say.

I've been having an absolute blast playing through this game. Multiplayer released just over a week ago now as well and that is just as phenomenal. I've got over 100 hours on Spelunky HD and I've played almost just as much on the 2009 release of the very original. I have to say that this is the best release of the game. For entry level players, you might as well pick this one up. The other two are fun as hell but this is absolutely the best way to play Spelunky now.

There is so much content. Even the very base ending of the game will take hours (I haven't even beaten the base game single player yet). And after that there is so much to do anyway. I literally found out about more stuff in this game YESTERDAY.

It is almost a masterpiece. Unfortunately multiplayer still isn't in the best situation. Playing with friends is easy enough but you have to get used to lower FPS, and also you can't unlock new characters if you are with friends, which is probably my biggest gripe.

Despite all of that though, it's brilliant. Check it out!

Evolves on Spelunky HD's ideas in tons of creative ways. Super fun to play and (attempt) to master, all the new levels and mechanics and everything are great. It is punishingly difficult though, even more so than the original, and my one genuine gripe with the game would be that sometimes the level generation can give you a level that's actually just bad, which isn't something that really happened in Spelunky HD. I suppose the more sprawling, complex levels leave more room for bad generation, compared to the more simple levels of the last game. Still, a whole lot of fun, and one that I'm sure I'll still be coming back to for the forseeable future.

Muy buena música. Muy buena dirección artística. Diseño de niveles generado proceduralmente que hace cada run diferente e interesante. Mecánicas de juego increibles, siendo estas muy simples pero con una capacidad de expansión enorme, y ofreciéndo al jugador un gran margen de aprendizaje y masterización. Aún y todos estos puntos positivos he acabado abandonando el juego antes de terminar la historia principal por su alta dificultad.

En definitiva me ha parecido un muy buen juego y he pasado unas cuantas horas divertidas con él pero ha acabado volviéndose más frustrante que divertido, se lo dejo a quién tenga ganas de perder años de vida :)
