It works fine in Safari!
1. Very cool concept of using shadow mechanic, how smart! (a bit of bragging here, huh)
2. You used the concept as we did but the execution is just awesome, well done! I was really struggling to find a good realisation of the idea, and it also was kinda hard to organise all that was happening on the stage and on the shadow screen to make it clean and readable
3. The game blows my brain, very cool challenge
