Well, there are my first impressions:
1 - The game shows a weird world, full of monster-pills, an hipnotic music that makes you sleep while play;
2 - The scenario has only a texture, I believe the author had not time to increase the texturization of all materials. So, we must wait for updates;
3 - The perfornace of game is poor on my machine, and my configuration not is so poor, I have an Intel Core Quad CPU 1.61Ghz, with a videocard GeForce GT-610. So, this game, that looks light, would must run free of lags, but when the blade appears, the performance suffers an incredible slowdown, almost stopping the game! The author needs to see this. I don't know if the reason of this problem is my machine, I believe it no;
4 - I feel absence of an intro story. This is not mandatory, but it will be welcome to understand game context.
However, the game brings a good promise of fun. Hope the author can turn it into a successful game.
For a game made in two weeks, it is awesome.
Congrats, in name of all brazilian developers!
