The switching of up and down was a little janky at times, but when you get past all of the disorientation you can easily manage. The overall gameplay was fun and immersive. The puzzles were not too hard, but forced you to stop and think, and then comes the contrast where intense time limits are added. I makes for diverse and fun gameplay.
The story is simple, but very effective as i allows the player to follow along and empathize with the characters. I liked the hints about what happened very much, but I can not help but wonder, what was the key for? I did not quite catch that.
Graphics were good, audio too, but I am mostly impressed by the great performance considering the constant changing of gravity. Awesome!
Great work, I will be looking forward to your future projects!
