Based on the title provided, this appears to be a specific script or mod for the game High on Life (or potentially a niche Unity game mod). "v0.8.0" indicates it is a work-in-progress build, and "DiDongo" is the author.

Since this is a specific, user-created modification, there isn't a widespread official manual for it. However, based on the typical structure of DiDongo’s mods and the game mechanics usually associated with "Mental Blast" or "Negative Power" concepts, here is a helpful guide on how to get the most out of this mod.

The Verdict: Should You Play v0.8.0?

Play this if:

• You loved Hellblade: Senua's Sacrifice but wanted less story and more mechanical dread.
• You think Dark Souls is too forgiving.
• You want to experience a game that actively fights against your survival instinct.

Skip this if:

• You have photosensitive epilepsy (the Layer 3 "Void" strobes are intense).
• You get frustrated when a game takes away your tools.
• You prefer clear objectives.

2. New "Memory Leak" Enemies

DiDongo has introduced three new enemy types that directly interact with your Negative Power:

• The Echo: A mimic that copies your last movement. You cannot kill it with positive force; you must drain your own health to confuse it.
• The Gaslight: An enemy that does not damage you, but instead temporarily replenishes your sanity. In any other game, this is a blessing. Here? It de-powers your Mental Blast, leaving you defenseless.
• The Id (Boss): A giant, weeping fetus made of television static. To beat it, you must friendly-fire your own companions (if you have any) to generate enough Negative synergy.

How to Download and Install

Mental Blast Negative Power -v0.8.0- By DiDongo is currently available exclusively via the developer's Itch.io page and the "Strange Horizons" Patreon tier.

Installation Notes:

1. Do not install to your Program Files directory; the game needs write access to modify its own .ini files (used for the permadeath flag).
2. Antivirus software may flag the .exe. This is a false positive due to the memory-draining scripts DiDongo uses to simulate the "Mental Load" mechanic.
3. Backup your saves.dat file before playing if you value your progress.

Version 0.8.0: What’s New?

DiDongo has been iterating on this concept for two years, but version 0.8.0 is the first build that feels "complete" in its incompleteness. Here are the key features of this specific release:

13. Recommended experiments and next steps

• Map resonance windows across varied environmental AF profiles.
• Validate inversion thresholds across receiver varieties.
• Explore closed-loop control strategies with conservative safety envelopes.
• Collect telemetry to refine AF propagation model and reduce model error below ±5%.
