Good job for the submission!
Here's some feedback:
The game uses mechanics (as you said vamp survivor-like) that are already established, though it does not expand much beyound having the rent system and moving shop (which is more of an annoyance - more on that later).
Unfortunately you added a HP system, which means if you are doing good on money you are going to struggle with your HP, while this is interesting it kind of trivialise the interpretation of the game as the rent never scale, I wisht he losing / winning cndition was handled more gracefully... Also the moving show means that if it spawns in the middle, there is no way to reach it and upgrade your run, and why does it not stop the game? It's way too fast paced, I just found myself quickly buying whatever was available before leaving...
Audio is pretty simple.
The art is quite cute! Good job, I like the doodle vibe!
The game could you some polish for the gameplay...
Good work!
