Whew, I saved the server and data! That was a very hectic, but fun experience. I really like the idea of restricting the order of actions, while still being free to time everything however you want.
I can see the potential in coming up with strategies for different levels if you plan on developing the game further. I managed to beat the current level by prioritizing health and shooting, and cheesing it by spamming dash to get back my attacks quickly, so having more layouts to make each card useful would really bring the whole idea together nicely.
The music and the player character both feel very wholesome, and then you're fighting all these mean viruses, and I don't know where I'm going with this, but I liked it.
First time I played I gave up on my run because I didn't know what I was doing and made the game really hard for myself by building a bad deck. Maybe some way to change it without restarting the entire game would be a good idea.
One thing I didn't notice at the start was that the platforms didn't block enemy bullets, so me taking cover wasn't helping my chances of surviving. I'd also like to be able to slash viruses below me while standing on the platforms. I think that would make the slash card feel more useful.
