Renders are awesome, story is also not bad, "but"... it's one of the buggiest crap that I've seen so far!... Especially Load/Save option. Was it really so difficult to make it work properly??? It didn't work normally in verson 0.3, it doesn't work properly in version 0.4 either!.. Sometimes "Save" and "Return" options just disappear!.. So 1) You can't Save. 2) You can't EXIT menu and return back to game. The only option left - to load one of the saves that you were able to make when it still worked... so: graphics - 8 potatoes out of 10, story - 7 potatoes, coding - 1 potato...
PS. FFS, switch to Ren'Py, dude!.. if you can't use Unity... just a bit of advice...
