Nice little puzzle game! Deceptively simple! I almost got myself stuck and had to start over a couple of time!
The one thing I would want improved is the controls. I'm a lefty. So combine wasd and mouse look along with using the space to interact - really hard to do while still using my left hand for the mouse. Since this wasn't an action game I just switched hands for the mouse and awkwardly played. Anway, please consider also supporting arrow keys too. And don't forget that there are alternative keyboard layouts in the world, so wasd might not work for righties in other countries. The ultimate would be to allow people to change key bindings, but this is a game jam after all, and so can hardly be expected.
I made and first-person game too! If you haven't tried it yet, please do and let me know what you think! Thanks!
