As others have said, this is a bit of stealth, but more puzzler to make sure you have the correct type of enemy in the correct position for the next few turns. It only has 7 levels, but each one takes about an hour or two to get through, especially at the harder levels. Basically though, it's a turn based puzzler with very minor upgrade options for the 4 character types.
It took a while to connect with the game, but once it clicked on the initial character loadout I was able to complete the 4 areas. The idea of the game is similar to Into the Breach with 4 areas with different enemies. Beyond the four areas and being a roguelite, the games are pretty different. As others have mentioned, movement is key. You gain abilities by moving long distances, and use character placement so that one attack triggers your partners to attack as well. It's a lot of fun, and I think the new characters that keep unlocking should be interesting.
The 2 hour average definitely fits this story. There puzzles were very easy, with only one confusing me since I didn't understand the mechanic for a little while, but I figured it out. The story was really good, and i liked the final boss battle.
The fighting so far has been really easy, but everything else about the game has been incredibly fun. As others have said, this is really a visual story with platforming and puzzles. It's something like a light Tomb Raider that has a lot of conversations with the supporting characters, and there's never any repetitive dialog. I don't think I'll be hunting for all the hidden items, but I really enjoy the story.
The missions are almost identical in how they play out, where you try to destroy bots and collect swag, usually before a timer gives out. It's an incredibly fun tactical game that really expands on the original game. That all being said, the travel between locations is significantly different. Instead of jumping between star systems, you're piloting a sub that moves above and below water, and has some real-time combat when you come across enemy vessels. The story is somewhat interesting, but mainly is just there to guide the gameplay along. Definitely a great game with enough extra capabilities that I may come back after I finish to try a harder run.
