Build your deck through 12 battles & 3 bosses. Everything is on a 2D grid, so you'll need to use terrain elements and positioning along with card synergies to triumph. Use stickers to upgrade your cards in a variety of ways.
you made a very good game! I should add "recovery cards" to gain more life points, as suggested also @Tails_Strife. I was not able to fight the boss. My tip is also to improve the buttons in the main menù. they are very different from the others in the gameplay. Nice idea and good design. Very good pixel art and animations!
I like very much the design, and the gameplay mechanic, a mix between chess strategy and rouge like, also if for me you should balance a bit, at least find a way for regain lost hp and nerf a bit the first boss, it's not easy to face an enemy that can do 8dmg for turn, hard mobility and too less action points
