I recently picked up Fights in Tight Spaces and have put a couple hours into it - it's an interesting mix of Slay the Spire and Into the Breach.
You're playing as a 007-expy, moving from one location to another, usually with branching paths that give you a choice of options of where to go. Along the routes you take, you'll hit areas where you can either refill/increase your health (hospitals) or improve/buy/remove cards (gyms) using money earned during missions. Each campaign ends with a boss fight. You keep your deck between campaigns, and, including the tutorial, there's half a dozen before the end of your career.
During combat, your character is - at least as far as I've seen so far - always in a one-against-many scenario. The only friendly I've seen so far was a civilian I had to protect, who just cowered in place. You're able to fight off the hordes of thugs, criminals, and ninja - many of whom are wielding weapons of some sort - because they telegraph what they're going to do, and you're way more mobile then they are. You've got two currencies - momentum (energy) and combo. You start each round with 3 momentum, cards (that I've seen so far) cost between 0-2 momentum. Each time you play an attack card that hits an enemy, you earn one combo. Playing a movement or defensive card will reduce combo. Some regular cards get stronger the more combo you have, others will deal a multiplier of your combo, but reset it to 0. Some cards have a combo cost - they can only be played if your combo is high enough.
Much like Into the Breach, positioning is everything. Enemies can be pushed around, bashed into walls or obstacles, or even thrown out of the arena (resulting in an insta-kill), if you position them correctly. They can also be persuaded to punch, stab, or shoot one another, if you sidestep or push them correctly.
One of my favorite moments so far was on a boss fight: Two of the bosses' minions had push attacks that went off automatically if anything stepped in front of them, and they just happened to be facing each other, one space apart. I was able to kick the boss into one of the minions, who pushed the boss into the other minion, who pushed him right back, resulting in a good chunk of the bosses life getting drained.
The game seems to reward glass cannon builds - many enemies have nasty effects when they hit you, some ignore armor entirely, and the values of block cards means that often, even if you block, you're likely to take some damage anyway; better to just step out of the way and dodge entirely.
Overall, I'm enjoying it, but I'm glad I picked it up as part of a Bundle, as I don't know if it has the staying power of StS.
