DarkMaus

"DarkMaus is an indie action RPG with challenging, skill-based combat that punishes careless play. In DarkMaus, you play a lonely wanderer searching for what’s left in a corrupted world. The odds are against you – you will certainly perish.

Death Echo: Each time you die, an ally ghost is summoned that retraces your steps, fighting by your side. With time you can collect multiple ally ghosts and choose their weapons for extra strategy opportunities.
