Oh my gosh, this is great on so many levels.
Just for starters, I'm a total sucker for the trash mammals that scavenge through the waste of the anthropocene (and these ones in particular are adorable in the game art). <3
But more to the point with gameplay, while the tactical combat is fun and engaging, the upgrade system is just *chef's kiss.*
Firstly, I love the fact that any boons that you aren't purchasing from a store are a choice between two different ones. It makes it so much more immediate and engaging than an option you can reroll, especially if they're both boons you could really use.
Secondly, the digestion tetromino puzzle system for stat boosts is also so engaging. Because you're left trying to figure out whether you allocate the stat boosts to specific characters in order to shore up their weaknesses or play on their strengths or prioritize getting those bonus stats for the whole group.
All in all, the design of this whole thing is stellar and shows a large amount of thought and care went into this. I've already wishlisted it on Steam and will likely be getting a copy on there once it's fully released for sure. I usually don't tend to buy titles if they're still in early access, but I very well might make an exception here because this is something special alright.
