Thanks for taking the time to play my game, :)
I am absolutely thinking of continuing this project, I like how this turned out given the time restrictions. The level scaling is a big issue I am working on, I have already added (on my local dev build) the ability to save up gold to buy costlier upgrades and a few minor adjustments to the metadata. I really appreciate your feedback and I would try to incorporate those!
PS. I completely forgot about sound till the last minute and it was too late by then.
