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 :<)
