Nice game! I succeeded to get every ending :P
I like the idea of changing the character’s sprite when you get hit by a stop.
Great work!
Thank you and good job!
I did that so there wasn't any HUD and I did it by having four sprites on top of each other with some particles too.
One empty hearth for background, one red hearth with animations (for each time you touch a stop sign), some spikes that appears around the hearth (for each spike you touch) and a purple hearth with an additive effect.
