“I just can't stop playing this game; I never get tired of it. I love it so so much. This is the best deckbuilder on Steam.”

“Pretty solid legacy-lite deck builder with space animals. Satisfying to win a run, and the difficulty seems tuned just right. Rumor has it the story is quite touching, but I've probably unlocked only half of the…”

“A truly impressive evolution of the deckbuilding rougelike genre. The addition of movement and variably defended segments adds so much interest to defense beyond 'have enough block' yet isn't overly complicated at all.…”

“That I won my very first run tells you this isn't a super hard roguelike (unless you turn up the difficulty modifier). That I loved every second of the 2+hours it took tells you how much fun is packed into the game. Not…”
“Phenomenal game. I typically don't like deck builders, but the art was so good with this one I wanted to play it anyway (and the deck building ended up being fun too). Thank you for making this gem!”

“The music during the crescendo of the story is really haunting and beautiful. Very well done deckbuilding game. I would welcome more cards and artifacts in the pool.”

“first run was quite enjoyable but then as there was no progression whatsoever after just playing for one hourr and newarly clearing three stages it was jsut not fun to go through all this again without any progress.…”
“I guess it's okish overall but as an avid card game player I found myself almost immediately bored. Cards and their effects feel meh and the mechanic of dodging left and right just does not feel compelling to me.”
“Much like Shogun Showdown this rougelike deckbuilder focuses on movement as a resource and vital part of your board planning. It is a very fun mechanic although I'd admit not for everyone. Gameplay loop is pretty…”

“[h2][b]A pretty nice and solid game.[/b][/h2] Here are some aspects that are neither bad nor good, just for your information: ☄️ no meta progression (no bonuses to unlock, only new characters to unlock in the first few…”

“The overwhelmingly positive rating is well deserved on this one. This is a game that knows what it wants to be, and pulls that off nearly perfectly. The synergies are fun to build, the story is well integrated into the…”

“This is a great game! I wish it was a little longer, although I could play more if I wanted to, but the time I did have with it was amazing. Like all deck builders, some of the decks weren't for me (or maybe weren't as…”

“Is this game good and fun? Yes. Is it great? I don't think so, but I'm not a huge fan of card roguelikes/lites so take it with a grain of salt. The story is quite good, though, and how it is told mostly makes sense. The…”
“Pretty fun card game, nice lighthearted characters. A bit grindy if you want to see the full story though.”

This is not the first nor will it be the last in a literal swarm of games covering this genre. But there's something different, something special about this little title.…”
