“Heat Signature is a fun game that has a few issues - think Hotline Miami meets FTL for the general vibes. Up front, this is a great little 'install and play in short increments' game - 20 minute play sessions are pretty much the best way to play this, and it can be really fun…”

“One of the most fun and (optionally) challenging roguelites ever developed! Simply watch the trailer on the Store page and you'll get an accurate impression of the stealthy/explosive/creative gameplay on offer.”
