Bugs:
The character can fall out of the map by walking far left or far right beyond the floor
Strengths:
Health bar, monster sprite, character sprites and the gameplay are done well
Weakness:
The platforms can be hard to time with the player falling too soon (or I'm not good at the game)
The number of mushrooms the player has collected could be displayed more clearly
Change/Improvement:
Add a start menu for the player so they have time to react to avoid the monster
