“[h1]An Addictive Space Heist Playground[/h1] Heat Signature is, at its core, a really fun game and that’s worth stating upfront. But before getting into the praise, there are a few issues that held it back for me. One…”

“Really fun, reminds me of FTL due to the pausing and gadgetry. The enemy AI can do some kinda BS stuff but it's internally consistent so once you get used to the enemy quirks you can figure out how to handle it. I'm not…”
“A fantastic game that pushes your brain to think of a solution to a problem that has no certain answer, definitely one of my favorite games of all time, the missions are simple at first, but quickly transform into a…”
“Go from, "Man, this game is pretty difficult and I'm struggling to do missions that are rated Hard or harder" to "I am the Alpha and the Omega, the only reason opposition exists is to be broken by my presence." The only…”

“suspicious developments have created something akin to an imsim, where the proc gen forces you to actually learn the rules of the game: how do you deal with shields? when do you use each gadget? how do you handle…”
“Hilarious as it is compelling. It's so easy to just lose hours to playing this game.”
“As usual, a fun, clever, engaging and all around a solid indie game. All the game they do are great, i can't wait for the next one. Worth the price, and the gameplay loop manage to not get boring. Its fun to think to…”

“This must be the best game made with Game Maker, and the best game of Tom Francis and Suspicious Developments. It's filled to the brim with great ideas and great execution of those ideas and is satisfying to play. - Can…”

“This game is designed to produce awesome gameplay stories. Yeah you can hack into turrets and doors, but what about swapping positions with a guard the instant he fires his gun so he shoots himself? Blow up a ship…”
“It's a good game, I really only had fun for around 7 hours but that's definitely worth the 3 bucks I got it on sale for. I don't know how these people aren't bored after playing for 50, the game just isn't well balanced…”
“obscure peak, cheap and EASILY worth it. if it was moddable it would be 11/10, 10/10 as it stands. takes like no pc power too.”

“If I could pay some money to give it 100 negative votes, I would pay. I bought it because it says it is real time with a pause. The tutorial starts with a tedious action exercise (with no pause and no sense to pause)…”

“It's fun. Top down Cyberpunk type missions where you can go in blazing or go with stealth. Not really any story. Perma death with perma progress. Fast paced, easy to jump in and out of.”

“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…”
