The first jump-scare was GREAT, it got me good! However after the 15 time, It became annoying.
There is a glitch with picking up the key.
The monster's design is good, it is hideous and disturbing!
There is a lot potential here! It would be awesome if you added a story, fixed the key glitch.
As the second level, remove the snowman, and keep the main monster.
Good effort, I am excited to see what is next, KEEP AT IT and I know you become great at this craft!
