Great to see a Godot being used. I love the music choice. Great job on the graphics. Nice parallax scrolling background. The controls are a bit problematic though.I couldn't get the keyboard controls to work but I was able to maneuver with a gamepad. I could only move left, right and jump so I couldn't get very far. Visually impressive first submission—keep making more.

Interesting little game. The jumping controls are a little bit floaty, and It took me until needing to jump to the second jump upgrade to realize that i could jump after walking off of a ledge, you might want that explained to the player. Couldn't kill all the things in the end screen as they were stuck having a mosh pit on a platform below (reverted above?) me that I couldn't reach, so I hope there was no true ending unlocked by killing everything there, haha. Other than that, giving all the enemies that do different things a slightly different look would have definitely helped with the visuals.

promising entry. I would appreciate some animation for the player when moving and some more optical diversity in enemies.

this game is promising but it has a couple of issues:

.

first, if you will give the player the jumping ability right away, why not just give it to them instantly?

the shooting ability is way too far, i couldn't reach it with my normal jump, so i got stuck and couldn't continue.

the enemies have some interesting behavior, i just hoped that it didn't feel like a big room with enemies all over the place.

all the enemies look the same, sometimes i couldn't tell which one does what.

the chair & the clock doesn't seem to have any purpose, i think i only used the clock once, but the i never found a place to use the chair, why?

level design is weird, there is a lot of floating platforms that feel of place with no purpose, maybe make the path more obvious and not confusing?

.

the music and the background look really nice, i just hope we see an improvement on the level design, well done.

Good first entry!  I was unable to escape the facility but had fun trying.

Some feedback on the controls.  Since I control both the Arrow keys and Mouse with my right hand, I found moving and shooting to be awkward.  I'd recommend either adding WASD along with Arrows for movement or add an alternate means of shooting (such as Space bar), or both if you are so inclined.
