This was really fun and relaxing! I love the art style! Only complaint is it's very bright overall and was difficult to read the white text on a pale background at times.
It looks great, and I love the music! I didn't really get to play it properly though as my mouse kept leaving the window and the controls would stop. Also, it needs inverted y-axis for people whose brains work that way!
This was fun! I really like the idea of cards as a defensive mechanic rather than the dungeon invader route most card games take! Having some tower-defence-esque traps and stuff was a really cool idea!
A really cool concept, and I really love the art! I found the controls were a bit "all or nothing" though, which made precision movement very difficult.
I really enjoyed the combination of platformed and pong/breakout mechanics here! With a couple more features as the level increased, I could happily play this all afternoon!
