Basically rock-paper-scissors with pretty pictures. Skill/strategy is a non-factor beyond choosing an appropriate deck. Duels can be lost without being able to make a single move, unless you're using a deck specifically designed to counter the opponent's. Horrible balance all around.
Honestly, it's too easy, even on challenge difficulty. With three or four rocket towers and some barricades I can pretty much go AFK and still win on any level.
When you make a game that's as reliant on movement as this, the movement needs to be absolutely perfect. Unfortunately, the movement/control in this game is sticky, random, and terrible, rendering the hardest difficulty pretty much completely unplayable within mere minutes. Horrible.
If you know that it sucks, then why did you upload it? There's nothing wrong with making a bad game, but only as long as you don't share it with the public.
What always bugs me about these games is that they reward you for simply farming kills, even when you have the capability to easily win the round.
Combine that with the slew of bugs, unpolished game play, simplistic, repetitive style, and an overdone concept, and you have one very mediocre game, here.
I don't really understand how people think the dangers aren't visible. There's a clear sound when something is about to fall, and most of the other hazards look the same. Once you see one, you've seen them all. I'm able to distinguish them without even noticing the sparkles.
As far as I'm concerned, this game is the perfect mix of artistry, simplicity, and game play. Excellent job.
Two words: UPGRADE. No wait, one word.
