NanoReaver is a tactical, ironman roguelike where your save is always live: the game writes to disk continuously, and when your Reaver’s core is destroyed your save is deleted on the spot—no do-overs, no save-scumming.
You pilot a modular mech with three slots—Head, Body, and Tail. Each part has its own persistent HP and traits; swapping gear never “heals” it, and damage follows the part wherever you equip it. Energy shards fuel progress toward boss gates, while one-use Energy Wells fully repair your currently equipped parts and then vanish.
Combat revolves around three-step W-A-D combos, scanning to identify an enemy’s core, and deciding when to exploit that weak point, commit, or flee. Roaming enemies with line-of-sight pressure you across each stage, and triplet HP bars for both you and your foes keep every hit legible at a glance.
The same ruleset powers two presentations: a crisp curses-based Terminal mode and a modern pygame Graphics mode with sprites, portraits, music, and curated TTS callouts—so you can play in whichever interface fits your mood or hardware.
