I've been looking forward to this release.

Crystal Caves is not a bad game, but its age can make it a bit difficult to get into. The developer of this HD version appears to have kept the game intact while giving the graphics and sound an overhaul.

Just look at the game's trailer (At about 1 minute into the trailer) when it shows the cutscenes! They've managed to perfectly keep the style of the art from the original, except now it is animated!

As far as I can tell they didn't add anything to the scene itself, which I consider a sign of respect towards the original work.

I'm looking forward to challenging the new fourth episode and the level editer looks like it could be fun to mess around with.

I suggest taking a look at this forum thread that covers some of the new features and changes:
https://www.gog.com/forum/crystal_caves_hd/crystal_caves_hd_fixes_and_changes_from_the_original_game

And for convenience here are those changes:
• Barrel added to the Episode 3 level selection area where you would get stuck if you played levels in the wrong order.
• Missing key added to E3L10 and E3L12 so you can open treasure chests.
• Unreachable chest in E3L09 can be reached now
• Candle pickup has a sound now.
• Fruit does not spawn randomly anymore, so the run for the top score stays fair. Instead, each level has 3 hidden triggers that spawn fruit nearby when you approach them.
• The green border when collecting all the crystals is back! For the players that don't know, the Green border indicates that you have collected all the crystals on the level and it is ok to exit.
• Some levels throughout all 3 episodes got additional bonus pickups & secret crystals. This was done to fill empty areas in the levels from the original game.
• Impossible to get crystal in Episode 2 is "slightly" easier to get now. You still have to work at it!
• Whirlwind treasure trap...is it really a trap? Can you discover how?
• The remake features new difficulties - Easy, Normal, and Hard where Normal is the original difficulty. On hard, you get fewer hearts & less ammo but the score multiplier is bigger - this is for veteran players & highscore seekers Many of the other games product pages on GOG have a notice right at the top when the classic version is included with the purchase.

For example, BioShock has a message at the top of its page that says "BioShock Classic is included with your BioShock Remastered purchase".

They should do the same with Crystal Caves HD, hopefully someone will add this quickly to prevent any confusion.

If Rick Dangerous 1 & 2 are released here on GOG I would buy them. ^_^

I'm also hoping that this remake of Crystal Caves may mean that we'll see an HD version of a similar game called Secret Agent as well sometime in the future.

Kind of looks like the Commander Keen games. Makes sense, as they were made by the same dev.

Weird. The website couldn't decide whether or not to give me the 25% discount but I finally got it. I'm guessing the discount is for owning the original.

HD my ass.

Here you go.

Commander Keen was made by Id Software but Published by Apogee (Keens 1-5), Crystal Caves was done by George Broussard and Frank Maddin and then Published by Apogee when George joined up with Apogee.

Thanks for the laugh. :)

Awesome! I hope a native linux version will be made at some point.

That would be great!

Since the original Crystal Caves runs in DOS, can we assume that Crystal Caves HD runs in Windows?

Yes

Sorry for a bit of necro but this release is superb to the max. I was kinda scared of the original as a kid since its difficulty levels can be a pain to master. But this overhaul, the colors, achievements... simply putting: perfect.
The chiptune fits nicely for y'all purists to the top and I didn't find it (and the game as a whole) to be just a fresh coat, nope not at all.
Like many of us here I'm "stuck" at home, thankfully so I'm one of those seeking a great virtual challenge (clichè, I know) and I did find one in CCHD. Give it a try!!

It actually looks quite nice, but I still can't understand the name. An "HD" version that has art at the same resolution as the EGA original.

I can't believe how Emberheart Games didn't get the rights to call the game Crystal Caves All-Stars since it's in the same vein of this collection ;P
