Definitely a good set-up for a Clicker game, but right now it leaves a bit to be desired. In case you're planning on continuing work on this game / a similar one, here are some points to consider:
- The lack of upgrade options makes the score increase feel redundant quite quickly.
- The Christmas theme feels a bit shoehorned in. Outside of this jam, it might as well be removed entirely.
- Purchasing multiple upgrades in a row (as one is wont to do late in a Clicker game) causes a rather ugly overlap in sound effects.
- The UI is not all that visually appealing.
I'm sure that with some work, this could grow into a more fully-realized game, so keep up the work!
