I finally got to play this! Nicely done :)
This game looks incredible. It's amazing that one person can make a game with such visual fidelity in just a week. Truly impressive. The game was dripping with atmosphere and felt near-cinematic, especially with the nice camera swing in towards the action when combat starts. It says something that you're able to pull off that camera adjustment without causing motion sickness - something I'm prone to with wildly swinging cameras.
Once I got a hang of the combat, I stopped dying to the first gun enemies. It felt a little repetitive at first though. I couldn't really distinguish between the left and right click abilities. Also, the game is way too dark. When enemies were on screen, there wasn't any good contrast within their cluster. I just saw a sphere of red light until right up close, and even then they were really hard to distinguish. And I could barely see the giant robot boss in the first area. If these enemies were telegraphing attacks, I couldn't tell. With all that in mind, all of the particles and effects just made the screen even harder to read, leading to some weirdly un-engaging content for what was actually happening. Graphics are great, but I couldn't make sense of it in the end.
Overall, this is still an incredible game for a single dev in a week. The controls are great, the combat feels responsive, and the camera work is outstanding. Keep up the great work and jam on!
