I mean it's a good concept, i wish it had more animations and was a bit more polished, but there is definetely some potential in it!

Me too...I only did it in two days - wish I woulda started sooner. Im considering doing a huge set of upgrades, adding controller support, an skill tree, character selection with skill-boosts on each character choice, more enemies with various attack/movement styles, random lands, goals, bosses, blah blah blah. Its not a complicated game, but I think if It had a bit more polish to it like you mentioned it would have a bit of an addictive play style - which kinda means its a big win for replayability.
Im glad you like where it started. Hope you stick around for the changes after the jam. :)
