Please fix thanks

I know...the game's been out for a long time so I doubt it will get fixed, but I'm only just playing through it and I was might confused in level 21. The objectives say to "Light a signal fire" except there is no signal fire in the level. What triggered that objective to be complete was to build the Water wheel.... https://steamcommunity.com/sharedfiles/filedetails/?id=2794595852 You even get an achievement for restoring this water wheel :D :D...

This game came out a year after Ancient Tribe Survival and yet... both the graphics and sounds are worse... and don't even get me started on the godforsaken beep sound when you collect an item which I can only assume to be a spectrum 48k homage. Seriously I'm 3 levels in and eyes are straining and my ears are bleeding. I'm not being facetious, this bloody game as managed to give me a headache in less than 15 mins. ...

but 12,49€ is a little high, have a few of the older games , have tiny graphics as well but priced at 3.99 to 5.99 which is affordable.
