Very uplifting theme for an incremental. Human suffering :-)

On a serious note, I dig the idea, it's original, it's different, at least it's not another nodebuster clone so we have to give credit to creative devs who try something new.

Still not everyone will love it, I'm kind of a nerd so I love numbers and it's fun to think about combinations, "first 2 of these, then 1 of these, then all in..." it's a fun gameplay loop FOR ME, but I'm not saying it's for everyone.

The art is nice, simple but colorful for a game jam and sells the idea.

It's a game jam game so I won't be too nitpicky, but I'd still point out a few things:

-No audio, ok, it's a game jam, surely will be added later.

-T to begin... why? this could be a very good mobile game, using T limits the game's potential. Also why T? why not enter, or spacebar, or esc. I actually thought "hey, what did the PROVIDE button do?" and I forgot the letter I had to press (T) so I couldn't open the help. Or why not just a "Close" button and then a "?" icon to open it? Seems like an odd design choice the letter "T".

-The theme is ok, but keep in mind not everyone loves dark humor, so maybe "slaves working in the mines" or "slaves working in the fields" could be better than sacrifices and even detailing how they died.

-It's too clicky at the beginning.

-The PROVIDE and ALL IN buttons (which apparently solve the "clickyness") ... culd be more clear. Foir instance, add another icon under each monument/site "ALL" or "Auto Upgrade". I guess if you say "ALL" it's clear you're sacrificing all remaining slaves. Also the buttons hide the legend describing how they died so they feel out of place in the center of the screen.

Overall I like the idea, the gameplay can be polished, a bit a more intuitive UI and probably a bit more family friendly theme and it could be a banger.
