Hey HunGARE! It's Snowy (because that wasn't obvious from my name lol). Didn't know you joined this Dare, so when I saw your response, I thought I might as well check your game out.
First of all, I'm really sad the game was only 40 waves long. It was a fun little game with an interesting premise, and I enjoyed playing it all the way through. I was disappointed (maybe disappointed isn't the right word... 'surprised'?) when it stopped after about two minutes of playing. Man, did I wish it went on longer...
The graphics, though not revolutionary, were great in their own right. The simple representation of everything made sure it was apparent which card was power-related. They were simple, efficient and - above all else - adorable.
The music was great to such an extent that it actually kept me waiting to start up the game to hear the entire track first. It carries that electricity/power feel fantastically and I feel like it fits the entire game very well. The only thing that broke it for me was how it looped. The end of the track and the beginning didn't feel like a natural loop to me, which is sad, because I loved the music.
I did think it lacked some difficulty (then again, I love me some unforgiving, challenging games). It played through it twice: the first time I pressed the right buttons as soon as I could, the second time I started by letting the bar drop down into the red. I found it was really easy getting it back up, and that the power drain overall was really slow.
Overall, You did a great job at the game! I still wish it was a bit longer and more challenging though...
