Loved playing the game! It's a genuinely fun take on some of the most abstract concepts in Physics, and I really enjoyed the way they've been used in the game.
Technically, the game is very well put together. The Art, Sound Design and Visual Design complement each other very well. Game systems and mechanics have also been coded really well, and perform consistently across the board.
I really enjoyed the difficulty curve over the three levels, and the Challenge level really does live up to its name haha! The game does have some minor bugs, but I did not experience any major crashes or game breaking issues.
Overall, an excellent effort with well designed systems, a cool visual design, and novel game mechanics. Can't wait to see more of this game.
