I absolutely adore the graphics of this game, the simplistic pixel style is really really nice, especially for an idle game. I love that the sprites are so simple but clean, especially the wizard is super recognisable for what it is despite being so small!! The main palette is gorgeous too, the colour scheme has that sorta mystical vibe to it. The music is a nice choice too!
My only issue is that playing the game causes my computer to heat up over time, its gradual but I do keep having to scroll down to the comments to 'unload' the game to give my computer a chance to cool down. Now my laptop is pretty old and this does happen with some games, I haven't seen any other comments about this issue, but I figured I may as well mention it while I'm down here waiting again! :P
I did see someone suggesting a breakdown of the resources income, I can definitely get behind that. Currently I'm struggling a bit to decide if e.g. a druid is worth buying, since I can't see the amount of wood each individual one gets me. But that is a pretty minor thing!
But yeah I really like this game!! I was surprised to see it was a prototype, I haven't finished the demo yet but it seems pretty fleshed out so far :D
Edit: Oddly, after prestiging for the first time, my computer seems to be heating up fairly faster :0 I'm not entirely sure why, might be a coincidence??
Edit 2: Ok no it's definitely heating up faster, that's so odd :0 Maybe I just have more sprites this time around(?)
