Overall very well done!
The game felt pretty good to play, and I especially liked the gloves and how the gun felt to shoot. The player character felt very responsive, and it did what I wanted it to do. I think that the level design was quite good as well. I never really knew where I was going, but I always seemed to be heading in the right direction. I also liked the music, it really helped set the tone of the game.
That being said, I did run into a couple of issues that I encountered while playing the game. I'm not sure if you all will be continuing the project, but I thought it might be helpful to list them below. For context, I played the Web build.
1. Every time there was a scene transition, the music would pause, and constantly play the same sound over and over again during the transition between scenes. It became annoying when there were several scene transitions in a row, like using teleporters to another room, just to use another teleporter again.
2. This didn't really bother me, but there were very thin red lines that appeared in various places that looked out of place, like when I would land on a platform, or some blocks in the scene would just have them.
3. For the final boss chase (which was quite fun/challenging), the game would take me back to what I think is the last segment of the chase over and over again after I thought I escaped. It happened in the segment where the normal enemy also chases the player for a bit, and there is a vertical section at the end where the player has to rapidly climb up a pipe "ladder". If it helps, I can grab a screenshot of what I'm talking about above.
I just want to reiterate that overall I think that the game was very well done, and I enjoyed playing it.
