Pretty cool game!
I love that you took the time to create a tutorial level, nice touch. Same with the humour in the story at the start.
The feeling I had with the gameplay reminded me of Home Alone 2 on the NES. I know it's a bit cryptic (big sprite with a high jump running around a hotel filled with bad guys)!! There's 1 thing I wished the gameplay had : a reward when you complete a level (maybe a time boost), and maybe a penalty if you get touched by zombie. I kept running back to the door after entering too. Minor thing but it could probably be fixed easily!
I had a fun time playing. The graphics were pretty cool. It looked like games I used to play on Flash 15 years ago!
Good job with your submission!
