I played this for only 9 minutes and already got annoyed by the controls. If you're going to be a keyboard-only game you should a) use the arrow keys for movement and b) allow keybinds to be changed. Using WASD + Tab + JKL is really awkward, especially because you have to hold Tab constantly.

The game itself is also awkward. It's top-down and has an artstyle that makes it hard to tell what things are. You have to hold Tab for everything related to the inventory. The tutorial poorly explains what to do. I got to some machine, i briefly saw some interactive option on it and then it killed me with a deathbeam. And this was the tutorial for switching targets? It's all very off-putting.
