Nice game, but oof it's a harsh mistress :)
I got 12 points - got to the third level and thought 'Wow THAT ESCALATED QUICKLY' - was like a repressed nightmare memory from my 80s commodore 64 pixel perfect platformer days. Got to level 4 without any deaths, but used up too many lives figuring out I need to jump onto the little platform on its upswing.
I'd like to see the rest of the game, but I'm not sure my heart can take it. Do you reckon you could add more lives or add a continue system with some form of 'punishment' like losing all coins?
