Extremely creative and I discovered more mechanics as I got pass 2-3 more levels! I did eventually get stuck on level 7 after a lot of tries... I will probably be trying it again :D However, the elements I have seen so far is a easy 5 star on creativity. I can't believe you created puzzles this intricate with such great mechanics in 4 days.
I really loved the math & puzzle element in the game. It really humbled me in terms of my puzzle ability haha. The difficulty is really challenging but it's a good challenge and mechanics are well introduced.
One small suggestion will probably be to combine the level narrative text with the gameplay, because the bright blue screen basically just flashes on when I click the level haha. However, it isn't any issue, just personal preferences.
Great job!
