Awful.
A decent concept, but executed extremely poorly. What's good about this game? The forest background looked kinda nice I guess.
The combat is horrible. The stun time and recoil aren't seamless. Enemies often trap you in unbreakable loops of fast swipes The same three enemies the whole game is repetitive and boring.
The game is full of glitches. If you die on the last boss and quit to the title screen it starts fucking up and spawning the boss in the first level. If you beat the game and unlock the cheat menu then you can't receive any more medals. I went for the 50 kills medal and after 20 minutes of repetitive hack and slash I didn't get anything. It's impossible to get the "you got all of the medals" medal because of this. Even if this was fixed, getting all of those medals in a single session would be a big fuck you to everyone who did it before. The rewards are unbalanced. Money is useless. There's literally no reason for you to collect money except for the pass $20,000 medal.
Your extra character can't knock down the bridge so he's useless for a play through and you can't use him for medals because he doesn't appear until after you receive the cheat menu glitch. The same looping music was annoying. The secret areas weren't really special or signaling at all, just seemingly random areas that you jump up to. There's nothing explaining the medals. Is one life a single life or when you get to the continue screen? Can you use cheats? Can you use the other character?
If you fix up the bugs and add a preloader then this could be a pretty mediocre game, even though it still wouldn't be fun. Good luck.
