Glad I stuck with this because this turned out to be a great game. At first I was very confused what was going on -- the only button that seemed to do anything was right-click, and only sometimes it would work. I guess then I read the description or tutorial and realized that the thing I thought was a scoreboard between rounds was actually a store (maybe I should have read the word "Upgrades" instead of clicking through it immediately). And then also those icons at the bottom of the screen were cooldowns, and you could only use a certain attack if it was lit up. And I thought, "wow lol I def would have realized that if I played more mobas or mmos".
So after that it was fun. I liked how your opponent got more abilities just as you were leveling up too. It def starts becoming trivial after a bit (ie once you get all the upgrades), but there's only so much you can do in 48 hours after all, and I must say it looks very polished and plays great.
But I see why games will put button icons right next to the cooldown meters, for idiots like me who don't realize those are my attacks that I'm allowed to use. Am I the reason why Skyward Sword had a giant Wii controller on the screen at all times? Am I the reason why Assassin's Creed Unity was 50% covered in UI HUD?
No, but I would've also maybe liked an indicator on your opponent's health, but that's a personal choice. Castlevania games for example don't give any indication of your boss's health, and they're popular despite the fact that I find the lack of feedback there frustrating -- like you give a boss all you're worth, and you won't even know if you've taken out 99% of its health and it was one hit away from death or if you barely scratched it.
I'm rambling now I think. But good game, great job, very nice.
