I had a blast and made it to 14 kills before dying using the "draw as many cards as possible" strategy which was really fun. Probably played for 2 hours at least.

This game hits me right in the genre that I love most, so thanks for making it.

Only suggestions (other than balancing) would be:

- allow keyboard controls like Slay the Spire so that I can hit 1,2,3,4 instead of the cards since my finger got tired on the trackpad

- allow more than 5 cards in hand or warn before doing something like using a draw 2 with 5 cards in hand. It was surprising in a disappointing way

- allow some way to permanently shred cards since the base cards and early cards end up cluttering the deck quite a bit. I understand that this might be intentional, but it was sad to pick early cards knowing that they'd be detrimental later

Super fun game! I've always liked the idea of procedurally generated cards/abilities, and I think you pulled it really well. I do think, however, that the 'gain gold from random card' and perhaps the 'gain maximum hp' effects need adjusting. If you get decent healing cards at the start, then you can stay and grind on the first fight indefinitely. I got up to kill count 31 with this method before I decided to start over.

Barring that, I've been stuck on 7, but I'm excited to try to get to 8!

It's a good game play - like it a lot! Also your tutorial - as minimalistic as it is, gives just the right amount of help to get smoothly into the flow. Great job!

Pros:

• Nice, clean art style. Very simple and yet effective.
• Selling mechanic is neat. Lots of potential for different strategies.
• Decent variety of cards, especially for a game developed in 7 days. 
• I liked the procedurally generated cards that scaled depending on how much gold you had.

Improvements:

• I found the cards quite hard to read. Specifically, its quite confusing working out what the card does depending on how you use it (sell, play, etc.) Perhaps add different icons or styling to the cards depending on what the card does.
• As aerial mentioned, the ability to remove cards from your deck would be useful later game.

Bugs:

• None that I could find ;)

Overall, very polished game. Good Job!

Neat game. Very addicting. My best run is 6. I wish there was a way to get rid of cards, like throw away one card every level, since those +1 health basic cards don't help much later on when the enemy is doing 12 damage per turn, but not sure how it would be balanced because if you end up with only draw card effects in your deck, you could keep drawing forever until the enemy dies in one turn.

Good and fun game overall. I really enjoyed playing it. Well done!
