The game seems pretty good so far, for a demo that is. the current state shows how strategic that later gameplay can be and the potential for high damage builds that can be swapped out in the middle of combat for a high energy build, or just an all around strategy to create and use energy at the same time. There is a huge amount of potential that i can feel, and even though the current state of the demo doesn't have the most content and doesn't really provide much replayability, there is still heaps of passion and potential. The pirate theming is also quite fun, and would love to see the future cards based around this theme (Would love to wield a cannon but maybe thats a bit too much) overall I did enjoy the time I spent on this game and will be looking forward to the future of its development, I can't believe I found this because youtube recommended me the demo trailer out of nowhere.
Also, remember to take your time creating this game and to not lose that spark of passion, rushing yourself and getting burnt out wouldn't be good, so take your time and swab the deck, don't get too many power hungry ideas now, mutiny is punishable by death!
