Nice ! I think the explanation screen does a pretty bad job but after one game or two it's way easier to manage your cards properly. Thanks for your feedback !
Thanks :D I must say it was quite a challenge and I underestimated the time need to code this. I wanted to add power on cards, but didn't had time. The card images are AI made, this saves a lot of time.
Increasing speed/damages, having some effect such as a piercing attack, slow, explosion or a double-side attack (this effect could aslo return against you considering the fact that you can kill yourself). Enemies could also be better with time (back shild, more life, spawning other enemies when they die).
I like the idea of projectiles wich can kil you, the high number of ghost makes the game unachivable but not frustrating, wich is nice. Perhaps having upgrades on your weapon could break monotony.
I must say I'm not a fan of die and retry games, but it fits the theme realy well. Moreover the upgrades are a nice feature wich permit to finish the game after several tries, nice game!
