Exit the building

This is my submission for the my first game jam and is my very first game. I was originally planning to add more but given the time frame, the fact that I have winter season for uni and I don't have the knowledge yet, I decided to stick with one level. Overall, I'm quite proud of my progress and I ended up making something that's at least a game. The premise is real simple, you're stuck in a locked building full of guards patrolling the area. Your task is to grab the key and escape without getting caught. Use WASD or arrow keys to move. Any tips and advice would be appreciated and I might come back to this game and attempt to improve if not remake this when I get better
