how do i open the game

Finally, after so long i found this game, been needing to play it for a while, thank god.

The glitch effect to cover the empty black of the out of bounds is biliant.
I love the wobly effect of hit enemies and the feel of the hammer when it hits.

Being slowed down when i get shot is a little bit frustrating since i have to get close to hit them.

The normal jump (the one in bounds) feels a litle too short sometimes, you could play with its height velocity and think about the low gravity to make more vertical levels (maybe a boosted jump out of bounds?) 

Keep the experiment alive, this is a little gem. 

With a little narrative it could become something revolutionary. 

You could also make it meta idk, you are literally breaking the "fourth wall", it could be an interesting starting point.

Also the dev comments could fit this narrative, you could use them as a clue to guide the player. 

It could become an horror or an adventure game with an out of bounds entity that must be eliminated, just saying : ^) ) 

Keep on keeping on <3

I love how meta this game is!  Regardless of the length of the game, this was a really well thought out experience.

uhhh, yeah. good game. 3 minutes and 46 seconds is my pb. but uhhh, yeah. recommend, good uhh, good game👍.

excited to play more

does this game have controller support?

Hi! It doesn't, sorry

this needs to have more levels 

this is SO much fun!

man this game has untouched potential

sad that its this small, this would make an amazing full game

yes is good please add more

can you release any early builds (I noticed it's name is NegativeSpace not "hammer_space"), so do you have any unused content or early builds?

Aside from the "Jam Version" - not really. It was only made in a week, so there were many cut ideas, but most of what we had time to make went into the game.


such a fun game, the concept is great, I love this so much!

This is amazing. I really hope you decide to continue the concept one day

This game is really fun but I just have one question: How do I get the second and third star? I see the star icons pained on the walls of the last few rooms but hitting them doesn't do anything, and I don't see anything when I go into the walls behind them.


I don't think I can mark text as spoilers in the comments, so... the painted stars are more of a hint than a pointer to where the stars are hidden.

If you just want to see where the stars are and how to get them, this run by brainsnug is a good demonstration:

Thank you

The Doom inspired out of bounds effect is really cool

Is this a Valve/Half Life inspired game?


Yes, a lot of inspiration came from fiddling around in SDK tools for GoldSrc and Source games!


Played this after funky mentioned it. I don't know if I want to see more reset-puzzles or glitchy movement tech.

Me too, me too..


Awesome game! Any chance there'll be more?

Make a mode where the guards don't know how to use a gun so instead of shooting you they just stare at you menacingly. The new mode should also make it so that you can't fall into the void when stepping out of bounds.


What a cool idea for a game mechanic! Can't wait to see more.


This is a really interesting and solid foundation, I can't wait for more


 this game is fun :D

I love the concept of the game. It's pretty fun so far and it reminds me of Portal, one of my all time favorites. I would love to play a longer version.


In love the idea of this game! I'm very impressed and it's also fun and eerie! Keep it up 🙌

Absolutely in love with this. One of the most fun games to route and play through in years.


The game is very original. The idea of the hammer to generate bugs in the game and that being part of the strategy is something that impressed.

It is also a very fun game. Congratulations!! 


really fun and unique mechanics in this and the level design uses them really well! would love to see this expanded with some more levels someday
