A good version of the 'idle clicker' genre, that does balance between clicking and idling pretty well. Progression is quick but not too quick where you can complete the game quickly. Got a good visual style and kept me fairly engaged for a while so well done.
Some of the HUD elements seemed to be a bit wonky, both the Sword and Staff look like they cost 1E+08 which I don't know if that is intentional. In addition, whilst the graphics were nice, I think that some animation and feedback to clicking rather than the slime briefly changing color would go a long way. A lot of idle clickers have something visual happening or a tiny 'meta-game' like clicking a quickly appearing object to click for bonus points to keep the player engaged outside of the core game. Whilst that is possibly out of scope for the timeframe, it is a consideration that maybe should be thought about. Finally, is the way the game is exported and accessed the most efficient or best way for a hyper-casual audience?
Overall, being able to make a idle clicker isnt as easy as people may think, especially regarding balancing both aspects of the core game. So having that done well is commendable, and with some additional polish and expansion I think this is something that could be marketable, great work!
