Thanks a lot ! Yeah, the time added by the coins changed a lot while I was making the game, I tried every value between 1 and 2, and made a last minute decision on 1.5 :')
Yeah, it was the objective at first to make it winnable in 7 seconds, though I didn't have enough time to think about level design to make it possible. Oh well ! Might make adjustments when the ratings are done.
