Where have I seen this before?
Whether it was intentional or not, I felt like your game had elements of others. For instance, the unlocked room at the start looks a lot like Sam & Max's office. Outside by the garbage cans, the drunk on the floor looks like the owner of the chicken restaurant in The Curse of Monkey Island. The main character himself is a mixture of George Stobbart (Broken Sword) and Guybrush Threepwood (Monkey Island). As I go through the game, I'll wonder if I'll come across more like this.
Anyway.. the puzzles are pretty good, but the background music is a little tiresome. Maybe next time, use different music in different scenes? Aside from that, a pretty okay submission.
