Once I got the hang of the controls I liked it! Shooting at enemies I couldn't fully see in the dark hallway was pretty cool. 

In the room with the shotgun I think you forgot to add a killbox under the level -- I fell into the pit and got softlocked.

And it's probably a good idea to list the controls on the page, or some kind of tutorial popup -- had to restart to figure out how to pick up a gun for the first time.

All in all, pretty good for your first game jam, well done!

Great game! I really liked your first song ;)

Congratulations on releasing the complete game!

Some comments:

• The size of the iFrame (the block of the page that the game occupies) is enormous consider decreasing it to something like 1200 x 600, otherwise it’s very hard to interact with the page.
• When the character moves it’s sprit should face the move direction. It should not be super hard to implement but will add a lot to the immersion.
• The Mouse 0 is a bit of a strange naming, guess it’s the name of the input from the engine, but consider setting the name manually, LMB and RMB are common and recognizable abbreviations.
• There is zero feedback of the enemies state, you basically have to count number of shots required to kill the enemy, remember it and count every other time. Adding a simple progress bar would significantly improve the accessibility.

i really liked the visual style and idea seemed interesting, but i'm not sure why the enemies weren't being hurt when i shot at them
