Who is Tim? Why is he living in my house? Why do I need to pay Tim to unshackle me from the bindings of his store? I suppose 1 gold is a small price to pay for freedom...
The animations for the character sprites are smooth. Good job on that!
When completing the game there's a promise of a lot more dialogue, levels, enemies, upgrades, items, collectibles, and etc. I would heavily suggest focusing on your core gameplay (character movement, interaction, and combat) before moving on to adding more things into the game. You have a vision for what you want, but it's important to limit the size of your project to what your current game development abilities are. There are quite a few bugs and elements of gameplay that are unclear. There's nothing wrong with this; it happens to us all. However, you should focus on correcting these error before expanding your game. I think it would benefit you and improve your abilities a lot to work on what you have here until the bugs are gone and the gameplay is much more clear to the player.
On that last note, try to have someone unfamiliar with your game play through it in the future to see what parts of the gameplay they have trouble immediately understanding. This will be a good way to gauge which portions of your game need to give more guidance to the player so they know what to do.
I know this comment is quite critical, but it's not meant to be harsh. Creating things is tough so good on you for putting this out here!
