This is a cool concept, and with a little polishing/iterating I think it could be really great!
The pixel art is good, and the audio all works well. While it doesn't seem super deep, I appreciate having the short intro story to set the stage! That always works better for me than just a "start" button and then fighting. I especially liked the "comic-style" presentation.
The gameplay itself is pretty hard. i had trouble keeping track of my spells and shuffling fast enough, especially when dodging/avoiding got more complicated. That said, some of this may be on me. I'll probably give it a few more rounds later and see if I can't push further. But I do think the gameplay feels like it needs just a little something else as it currently stands... I'm not exactly sure what, but something to smooth out the main loop of avoid/attack.
I encountered a bug that tripped me up on the third battle screen (i had gotten the "jump" card"). An enemy knocked me into the next screen, with the save-point. They then followed me onto that screen. I could walk back to the previous screen, but then I was stuck there, and the enemies didn't follow this time. I could no longer progress and had to restart.
Overall, I think this game has a lot of potential! What's here is already great work, and with some more dev time it could really stand out! Yet another Construct user too! I'm a big fan of Construct :)
