itch.io is now hosting a vast charity bundle called BUNDLE FOR UKRAINE

The funds will be split 50/50 between International Medical Corps Ukraine (medical aid and training) and Voices of Children (helps children cope with the horrors of war, PTSD, readjusting to school, and getting back to being kids)

Here's a few of the games which caught my eye:

SUMMER IN MARA—Upbeat adventure with inspiration from Ghibli animations.
INMOST—platformer with gorgeous pixel art.
SUPERHOT!—classic shooter with a time-move-when-you-move gimmick. I've only played the VR version which is beyond awesome.
ELDRITCH—one of the few first-person roguelikes that got it right. The simplistic artwork fits well with the lovecraftian theme and it's more scary than it has any right to.
DELVER—Another first-person roguelike that I have considered buying for a good while. Dungeoncrawl RPG with juicy pixelart.
LEARN JAPANESE TO SURVIVE - HIRAGANA BATTLE and LEARN JAPANESE TO SURVIVE! KANJI COMBAT—two RPG's teaching you Japanese. Could be fun, and if not, at least I'll learn something.
CURIOUS EXPEDITION—roguelike expedition sim with dice-based combat.
NINA AQUILA: LEGAL EAGLE—10 hours of insane VN courtroom drama!
DON'T ESCAPE: 4 DAYS TO SURVIVE— A mix of Point-and-click and survival mechanics in a post-apocalyptic world. Steam reviews sez "Overwhelmingly Positive".
TENDERFOOT TACTICS—Turn-based tactical adventure. Steam rating: "Very positive"
THE WRATCH'S DEN—Humble little roguelike Dungeonkeeper clone
BAKCSPACE BOUKEN—Retro dungeoncrawl with typing battles
FUTURE UNFOLDING—Some kick-ass visuals!

Good list of hidden gems.
The first couple of pages of the bundle lists more of the well known games.
CrossCode and A Short Hike, also Baba is You are probably the biggest games on there.
Also Celeste.

It should be noted that Summer in Mara is an artbook and Steam key.

CrossCode is great. I'm not sure if the itch.io version includes DLC though.

There are several games that piqued my interest but never got around to buying including, but not limited to Curious Expedition, Shattered Planet, Cosmic Express, Tenderfoot Tactics and Ganbare Super Striker.

The main one that caught my eye was Baba is You...kept waiting for that to appear on GOG, doesn't matter now I guess. I only had a few games on Itch before this, but a nice touch is that none of the games in the bundle appear in your library unless you download them.

Edit: Summer in Mara is a download. The bundle does not include any Steam keys, only downloads.

Oh nice. 990+ games for 10$ Is like $.01 cents a game.

I wish you could pick which ones you get. There are a few I'm definitely interested in but also quite a few I don't even want to touch. Still, that's a really solid deal overall.

Amazing bundle, and for a good cause. Got it.

Once again, itch.io marks the difference (and without unfairly discriminating anyone)

Do you have to add every game individually to your itch account like with their previous huge bundle?

There's also a TTRPG charity bundle around, but is far less attractive than this one (at first sight, I have only seen a game I'd bother checking out...)

On the description it says "A downloadable artbook + Steam key". The comments seem to confirm that too. Your library will only fill up with items you actually download. Everything else will remain hidden.

There's actually a few fairly high profile games in there. I know some of them are also on GOG and Steam, like Celeste and Sundered.

Wandersong is another adventuregame-like gem that caught my eye at the top of the list (and well worth it, but I've played it before already).

As I said, none of the games in the bundle appear in your library unless you download them. That's a good thing, and that's all there is to it, you just download the stuff you want.

That was probably true before, but not now. I'm here confirming that it's a download. There are no Steam keys for anything in the bundle; Itch specifically says that and it's true.

Celeste isn't on GOG though. That's one I had bought on Itch previously because of that.

Which one caught your attention? I'm on the fence with that bundle myself.

Shattered looks like a good game with an interesting setting. I'm not convinced by the rest of the bundle contents, though, but maybe I should take a deeper look...
