Did you know that after exhausting the ending dialogue and then clicking play again, the Start button on the title screen no longer works? I have 275 coins to get that fixed, by the way.
Parody aside it's a mostly good platformer! It has a common issue (or feature) with others I've played made in Unity where you can hit the side of the ledge and it resets the jump, allowing you to cheat (unless it was intended) up onto platforms you didn't properly land on. The ramp areas also let you launch yourself very high into the air which I hope was done on purpose because it's the best part of the gameplay. :)
The heart pickup sound is far louder than the coin and damage effect noises.
