Great job on this one! You’ve got a unique style and some clever mechanics. Can’t wait to see where you take it next

Cool game! I'm even hooked on it. I love turn-based strategy and card games; it's a great combination.

Overall, nice game! I feel like it might be a bit too difficult for some people cause the enemy amount scales a bit too fast. It would be nice to maybe add a difficulty setting, or just lower the spawn rate / add more cards for each turn. But despite that, I enjoyed the gameplay mechanics and distinctive visual style. Great work!

I like the concept and enjoyed playing it. I felt like the balance was off, since the enemies spawned much faster than I could move or kill them. It took me a little to understand the economy but was I understood it was easy to use.

It's a fun game, if a bit hard. My one critique is that after a lot of enemies have spawned in, you have to wait a long time while they all move until your next turn.

I dig this so much, I always loved card games in every incarnation, and a turn based RPG card game just thrills me, we need all of those we can get. I just feel like it feels unbalanced, at one point it becomes kind of impossible with the cards we have. Would love to see this expanded into a full fledged game, would love to play more of this!

Huh, very interesting! I've seen a lot of iterations on the roguelike deckbuilder lately, and "actually roguelike" is not something I've seen, which is wonderfully ironic. This is a fun take on the idea! In several playthroughs I was not quite able to complete the hack, though I did get close. I can see enough synergies in the cards provided that I'm sure I could make it with a few more tries, which is a great place to land on balance during a Jam.
The art and sounds are nice, simple but effective, and everything's weaved together pretty effectively all together. Fun and creative - nice work!

Got to 90%, I feel it's a bit too random for my taste (maybe that's the charm of that genre) but I still had a lot of fun and played couple times to try and figure out the gameplay loop. For a one-man job it's really impressive title!

The sound is pleasant. Though at some point it gets a bit scary how many enemies start appearing :)
It was fun—thanks for the experience!

Very clever game! Player is always in a state of "it's so over" when in fact you can get out. But it does snowball very easily and resources are so difficult to get. I'd only give 1 more movement to the player so that you don't waste too much time at the start. But it is so addicting I just can't stop playing. Want to try and beat the game. Thanks for making it, it's so fun!
Edit: I did it ^^

What a cool, well rounded game! Enemy variety, systems, card UI... That's a lot of work, seriously impressive to see in a game jam.
Gameplay is fun, early on it's quite forgiving, but then it keeps ramping up so the challenge keeps up with levels. Eventually I got overwhelmed, but I played for a good while and got a bunch of upgrades before I fell.
Great job, one of my faves this time around.

This is really good. I have not seen a deck builder take this approach to the combat system!

The art is so cool! Interesting idea and good mechanics, congratulations!

Really cool concept, an interesting cyber atmosphere was present, and a pretty clever challenge!



It's decently intuitive to play too!
Love the new description and images
