This game is so sick!! The creativity is off the charts with this one, and everything works together well to make a game that feels whole. I really liked all of the mechanics, as well as the movement as a whole, and everything felt really fun.
I like the idea of having "depth" to the world of a sort by using files to enter different worlds. With this idea, I thought that I would get lost a bit, but the blue arrows at the end of the great thinker rooms pulling you all the way back avoided that issue.
I agree with some of the other comments about the time limit feeling a bit limited though. I beat the game on my first try within the 20 minutes, but I felt like I had to rush through, and didn't have time to take in the world. That being said, time limit is well implemented, and I love that the enemies slow you down rather than having a health bar, as it ties into it really well.
I really like the combat, but one thing that could make it even better might be a little bit of flare to the box when C is pressed, just to give some indication that an attack is happening, and to make it feel more powerful.
The great thinkers are so well made, and really make me feel that sense of grandiose and scale, which I really liked. The rooms that they were in were always fun, and designed very well too.
Really well-made, and I enjoyed it a lot!! Great job!!
