By no means a bad game as far as simple flash games go, the main issue I have artwork is boring to say the least. Good artistic graphics can make a simple game you won't play for more than 5 minutes into something a lot more interesting.
As an aside medals appear to be broken for me, I have "Challenging" without having "Easy" and I received a score of 81 without getting the "Difficult" medal.
i don't understand the plot and the controls are facked.
Fun and addictive for a few games, that's worth 3 stars. I like the art style, the silhouettes look really nice but I kinda wish there was more to it, upgrades, new levels etc.
Also I don't know why all Unity games don't have a fullscreen button, it's trivially easy to implement:
Screen.fullScreen = !Screen.fullScreen;
Once those spikes start coming out the challenge level rises considerably! Doesn't matter how many lives you collect, once you get stuck it's over, which seems to defeat the purpose of that particular upgrade. But it really is a pretty addictive again, easy to keep starting over and over, and I like the idea. Simple new, with intuitive controls and pretty catchy/atmospheric music in the background. Nice work!
Its fun, but its pretty easy. The medals give you a lot of points, when they should give you much less. The music, though repetitive, fits the game. The artstyle is nice, too. not too much gameplay, but still an enjoyable experience.
