Im maybe wrong people to judge this becouse i didnt complete first level, first of all game is hard to understand and its just bad thing on gamejams. When i finalkly got the idea the gamne was just slow with no juice, feedback, enemy health, and it was very unbalanced becouse i think enemies did nothing and i got just moving cards in some turns so killing enemies was slow.... got boring pretty quickly. One last thing i need to say is wtf is this post processing, i see there is good models behind that color mess and its realy sad to not even see models clearly.
Sorry if i was too straight with my points but i dont wanna give honest feedback. Dont feel bad, its learning experience, i think you may have overscooped and run out of time badly, next time try something simplier or justy make sure you have enough time:D. Wish you all the best
