It looks like this:

How we fit the GMTK25 theme "loop"?
We fueled our game development with Honey Loops and put together this table to show the results.
| Team | Ate Honey Loops | Did not Eat Honey Loops |
| Picster | Yes | No |
| Sam | Yes | Stated the law of noncontradiction |
| Guy | Yes | Yes |
| Perfoon | Yes | Also ate Picster's gun textures |
| Cameron Paxton | Check out the OST! | Check out the OST! |
| SupaBubba | Yes in a bathroom late at night |
...also the time looping mechanic kinda fits the GMTK theme but that's secondary to Honey Loop consumption.
Note: we've intentionally left some of these weapons untextured as a test of your bug-spotting skills. Can you figure out which ones we not accidentally messed up on export?

You're supposed to wear shades while you play.
Did I just hear "I'm Liam Neeson and you're playing Deja Boom"
I only heard it once, am I just imagining things?
This is Liam Neeson, and you're reading this comment.
Steam release when?
It is the best shooter I played from the jam so far! Stands out from all the "kill your past self" ones and the absence of friendly fire just makes it more fun. Sound design is on point. Guns are different and fit different situations, the last level forcing the player to change them constantly. And katana is simply the best, scaling the buildings and ripping through enemies was satisfying, even if hard to control
One of the best entries of the GMTKJam2025!
