This is probably one of the most polished games in the jam.
A lot of programming effort clearly went into making everything here. the AI of the little miners, the juicy-ness of the mining, sound effects and buying stuff.

Obviously, id agree that the font color makes it just super hard to tell what im reading. 

Personally I LIKED the right click to upgrade. Def should have been something saying thats how you do it (Unless I missed it), but I like how it keeps everything to my mouse. 

Very well made and I liked it even though im not really a fan of incremental. Still great.
