Solid start to a simple gameplay loop. I played the half deck and was able to start and play through the game blind. Some more confirmation on what card I played would have been awesome instead of just a positive or negative sound cue. I also noticed the game would store inputs so if you accidentally pressed a direction twice you would instantly play through 2 rounds. The voice reader also held lines like selecting a deck of cards if you somewhat quickly switched through them, the voice line would lag behind on what you actually had selected.
Overall, good start with potential to add new mechanics like different deck setups, abilities like switching cards with the opponent, or other shenanigans. Thanks for sharing your game!
