You're obviously aware of the bugs now, from the comments, so I'll spare you those again! I like the concept of simple cards for healing and attack. And the graphics and sound were decent. Dunno if you'll continue on the project?

First, the viewport is WAY too small.

Next, when I beat the first monster he just made a earpiercing noise and then I couldn't beat the next monster.

The art style of the mons is good and good enough executed. The overworld is a bit basic.

You can tell this is a prototype, it's pretty bare bones and partiatly unplayable. On the minor side you have some collision boxes not ligning up with the tiles, seeming twice the size then it should be.  On the major side, the battle system is basically broken - it kept giving me only health up cards after a while, leading me to neither win or lose the battle (the AI did nothing), or after dying not giving me any cards at all.

Overall it needs some work and more game badly (also the music is way too loud :<)

It was a bit strange to play with the mouse, also I played it on the browser and for some reason the window was super small. Controls in the map feel a bit strange too.

I wish there was more to do! The card concept was a fun twist. I kept getting softlocked every couple of battles with no cards as well :(

I looks fun and the art is great, but I unfortunately got stuck in a battle without cards.
