Haha I thought the same thing when I saw your game!
I also feel that the time-based score system was a good idea since it forces the player to act faster, making the game a bit harder (at least in theory lol) but there is a bit of tweaking to do to make it a challenging game.
I've got 1500 but I played a lot in the last 3 hours of the Jam when testing the game 😛
Thanks for you comment!
