Nevermore: Natural Language Spellcasting

Cast spells just like your favourite heroes, without the typical restrictions of normal videogame spells. Discover and practice new spells against imp dummies, then join a multiplayer match to use them on your friends (may need manual port forwarding).

Base game uses GPT-3 to interpret spells, which will have significant latencies. Faster local models can be enabled by pressing the Use Faster Model button (requires Game + Local Models version).

Tech demo built on top of Unity's BossRoom multiplayer demo.

Controls:

• Left Click to move
• Tab to enable spell console, enter to submit spell
• Hold shift to enable voice recognition with Cortana (you may need to mess around with enabling Windows dictation)
• Once spell is ready you can cast with right click, provided you have enough mana (yellow means not enough, can wait for mana or try different spell)

Known issues:

• Local model may stop working after a match, requires a restart
• GPT-3 may be unstable, use local models instead if this happens to you
