Obra Dinn but for Battle Royale is a great hook, and I imagine The Death Game Report, currently a Japanese-only Steam release, will take off on its premise alone once it gets that inevitable English translation. (It's already got a healthy reception in Japan.) Reporting from the game's mother tongue ahead of the zeitgeist: this game, while unspectacular, delivers on that premise competently enough. There aren't any 1-bit dioramas here; instead, you're accessing records—the last thoughts of each deceased contestant, recorded by a chip in their head—through a Type Help-esque file system where you use deductions about the deaths to piece together file names and access new documents.

The game delivers on its premise—workmanlike, nothing more. The deductions aren't too challenging; the dev even takes care to bold any important information so you don't miss it. The only roadblocks, really, come from messy unintentional ambiguities in the text—points where the exact weapon or assailant is unclear and you have to play a combinatorics guessing game to get your set of three correct names, or bits where the means of death is kind of nonstandard and it's a struggle to find out how the game wants you to phrase it (despite some guidance in the instruction files).

I'll also note that there aren't any spectacular moments, like that bit in Obra Dinn where the scope of the game really opens up, or the carpenter's death there, or the death on the bed that reveals the twist in Type Help. (The way in which one of the big Problems is dispatched with an unusual "weapon" comes close, though.) The writing and characterization are likewise functional but unspectacular. The game's competent, and it deserves the English translation and wider audience I imagine it's getting with this barebones early release (the Roottrees and Type Help release path). It's a good few hours of entertainment, but a bit more imagination would've really sent this soaring. This gets the job done, though, if nothing more.

(It's also better than Type Help for not having a completely stupid explanation for the goings-on.)

You may encounter one death that's a persistent sticking point. Consider that you may have to figure out something additional in its regard.
