This is Hamachi, a resident who has lost his touch with reality and is now going on a murderous rampage.

Around others he likes to portray himself as a trusting, simple minded individual.
But when no ones around, he ventures out to satisfy his sick mandatory needs, taking innocent lives.

With Hamachi's urges to kill grow progressively worse, he slaughters anything in his path and while doing so, dodges the hand of justice every single time.


You can kill everything that you see. Or use your better judgment, and spare these poor innocent creatures. Your choices effect the outcome of the story.

I'm using Hamachi as a creative outlet for whatever it is I'm feeling in my head. My depression, personal experiences, people that I've lost, my anger. These feelings fuel my ideas. If this isn't your type of game thats fine, it was for me.

This is great.

A well made demo. I can tell that you take pride in this. Nicely polished, an vary in a cool small package.I think I enjoyed the music the most.

I can't find any cons in it.

Can't wait to see more. GGs :)

PS. I want ost ( especially what plays during the 2nd phase )

I can't even play it because windows block it because they think it might harm my PC and they block it so I am waiting for the report to come in because I reported this website is safe I hope I get to play soon.

this is just due to me using and compiling the game in Gamemaker 1.4, its a false-positive and you should be fine to execute. there isn't much i can exactly do about it right now though, to my knowledge. 

It's ok I will figure something out someday.

This game was a lot of fun. I enjoy the idea of there being more endings based on how you play, especially on a simple platformer. I am super excited for whatever happens next in this game. 

I'm super into this game. The idea of killing or not killing causing different outcomes in a platformer is great, I can't wait to see how it ends up. I played this for my Bloodcurdling Barrage, in which I do daily videos for all of October.

It doesn't seem to let me use the d-pad or stick to select things in the menus with a controller.

known issue, its temporarily mapped to 'select' i believe. 



I don't feel comfortable seeing basically the aestetic, designs, animations and the intro scene to the level, all from Kirby.

I hope all of that art is just placeholder or at least that you make clear that is a Kirby parody.


I am looking forward to the full version of this game brother.


Absolutely loved this chaotic little platformer. Loved the music, art and animation -- the blood animation is top notch -- and thought the writing was passable but could be cleaned up just a tiny bit. I look forward to more of Hamachi, I'm absolutely keeping my eyes on this.

here is my run i did enjoy a video the power up chainsaw and the chase 

hi.big thx for the game. greetings from rosti

Haven't played it. It's great.

How can you say it's great without even playing it? I've seen the videos and it "looks" interesting, but I'm looking forward to play it myself and confirm whether it's good or not my taste.


They could have meant that they enjoy the concept of the game. You sound really pretentious.


I'm sorry, I didn't mean to be pretentious or sth. No hard feelings.


I just did, it's awsome.


No worries, sorry. I probably shouldn't have been that harsh.
