Vaporum

I bought this as I love the old style Dungeon crawler games. I'd played and completed Legend of Grimrock 1 and 2 with my 11 year old daughter. I would do the movement and she would perform the fighting and interaction. Together we would solve the puzzles and talk about strategy. We're only part way through this and are loving it. It's tough but highly enjoyable.

Great dungeon crawler. Criminal that it hasn't had more attention. I saw it on Splattercat. Simple story, simple gameplay, but keeping me playing. I'm an old school Dungeon Master player on the Atari ST that I bought in the late eighties, so I don't fear the grid-based dungeon crawler game. And neither should you - it's not just nostalgia - it's a good game. A lot of these types of games are good. This one has a pause that turns it almost into a turn based game if you activate it. Recommend.

Ignore the recommendation and Read first:
Honestly, the puzzles, the story and the general feel of the game were a bit generic. Nothing too crazy to break your experience and want to stop playing but just underwhelming. It also unfortunately felt like a relatively lazy Bioshock wannabe story-wise (without getting into spoilers). Absolutely no issue with getting inspired from somewhere and wanting to emulate such a masterpiece, just could have been done a lot better.
Unlike other people I didnt experience any crashes, so Im sure it's compatibility issue/driver issue.
Overall I would recommend it, given how it was the studio's first game. It definitely wasn't a bad attempt and I saw there is a continuation of the story which I will give a try. Just, probably not worth the full price.
So if you want to scratch that Legend of Grimmrock itch and have a few extra dollars and this is on sale, that's a good way to do it, although iirc LoG had plenty of free mods that had better puzzles and story overall despite not having a "Fully-voiced main character."

Vaporum is a good old fashioned grid-based dungeon crawler. Everything you would expect is here - secret doors, puzzles, traps, and deadly enemies. You can choose one of three rigs at the beginning and distribute skill points upon leveling up, which allows you to specialize into one of a few available weapons and a style of fighting (being more tanky or relying more on gadgets, think spells, that deal damage).

Overall, I found the game to be pretty fun, with only a few frustrating passages. A lot of the story is voice acted decently well and provides a backdrop as you climb the tower. For around 10-12 hours of simple dungeon crawling fun, you can't really go wrong here and I definitely recommend Vaporum if you like these kinds of games.

Not as good as Legend of Grimrock, but still pretty good and scratches that dungeon crawling itch the way not even Legend of Grimrock 2 (aka "we want to be Myst now") could.

Remember games like Eye of the Beholder, Dungeon Master and Lands of Lore? This was clearly made by people who do. The grid based 90 degree angle real time combat is in focus here, and it's as fun as it was back in the day. There's a button to switch into a real-time-with-pause mode, I've been trying to hack it old school and I'm still having a blast. The enemy abilities and the gadget powers and weapons you get are beautifully designed to make the set piece fights dynamic and challenging.

There's puzzles and a plot as well, but this is closer to Dungeon Master than something like Legend of Grimrock 2. Just straightforward steampunk flavored raid and loot action.

Great game. Got some Bioshock vibes storytelling wise. Very nice puzzles and secrets. It wasn't as hardcore as Legend of Grimrock 2 - which is my favorite in the grid-based sub genre. But this isn't necessarily a bad thing as this has less opportunity for frustration and backtracking. So it has less of a feeling of accomplishment because LoG2 tests you hard. But it is still very satisfying because it still is challenging and engaging.
Do not spoil your game using guides. This game is about finding solutions by yourself. It is NOT an RPG or an action game.
It involves some elements of those but it is a game about tactics and timing (in combat), puzzle solving and finding secrets. I enjoyed it very much on normal difficulty and finished one playthrough. I don't see me playing it again, though. The mystery and the puzzles are solved, the secrets found - for me, that's it.
I used a gamepad for medical reasons. It takes s bit to get used to everything but they did a great job implementing gamepad control imo.
(Some tipps for people unfamliar with the genre: Time stop mode is mandatory in many situations. Use the map and make good use of the notes function.)
