Cavern Crumblers is a poorly made local PvP small screen arena shooter with a Mafia(?) theme as you fight up to three AI enemies (and no players because nobody in their right mind would actually play this). While there's a number of flaws here, the big game killer, apart from lack of any actual content, is sheer lack of polish and clunkiness. You can remap the controls, but you're basically forced into using a console peasant children's toy controller for any more than one player... all of which go back to problems with the core concept for the game, of course.
And polish... there is none. The UI is a clunky mess, it took me a while to work out how to add AI so I could play the game, wherein I discovered very quickly the same clunkiness pervades every aspect of the game.
From a technical perspective, the game doesn't meet basic minimum requirements that most PC gamers expect as standard.
While there are options to change the resolution for the game, all this does is scale up the simplistic 2D art assets used to make the game, which makes little or no difference to the graphics quality. Without any other substantial graphics tweaks, it's not possible for gamers to improve the lacklustre 2D visuals.
The game features somewhat lazy, simplistic "retro" looking 2D graphics, and it's hard to say if this is due to the age of the assets used, if it's a deliberate attempt for the game to look bad/retro on purpose, or if the assets are just, well, terrible looking. It does look like MS-Paint was heavily involved in the art design for the game. This is a bad thing.
Considering this is being evaluated as a PC game in 2025, such poor quality 2D graphics in the 3D era just aren't good enough, whether it's a deliberate design fault on behalf of the developer or they just couldn't manage to do any better, this is a compromise gamers shouldn't have to put up with.
The developers didn't design the game for modern gaming PCs, as such the display resolution caps out at around 1440p, there's no support for the state-of-the-art 4K or higher resolutions. The game simply won't look right on modern gaming displays due to this failure on the part of the developers.
This looks a lot like it was designed for consoles, but released on Steam instead by mistake. While this is on PC, it has all the hallmarks and deficiencies of a console game, from the clunkier than needed control scheme to the less than cutting edge graphics. There's 10's of thousands of PC games on Steam, and PC gamers deserve only the best. This might not appeal to many gamers due to the lack of PC-centric design. It's unclear why this never made it to the video game console appliances it seems to have been designed for.
These technical defects push this game below acceptable standards for any modern PC game.
The poor quality of this game is reflected by how many people spent time with it. At the time of this review, SteamDB shows the all-time peak player number was only 2 players. This is a remarkably low number, and now, the only player activity occurs once or twice a month, presumably someone loading it up to see what it is then quickly uninstalling it. Considering there's over 120 million gamers on Steam and well over 110,000 games for gamers to choose from, the overwhelming lack of interest in this low quality game is to be expected.
So, should you buy this game? Is this one of the best of the 110,000+ games on Steam?
Cavern Crumblers is relatively cheap at $4 USD, but it's not worth it. Given the defects and quality issues with the game, coupled with the unrealistic price, this is impossible to recommend. This is also competing with over 14,000 free games available on Steam, many of them far better than this paid product.
