Basic but decent spritework and interesting resource management even if it isn't the most complex. Only minor gripe is if you have two windows (PCs and Fans) open at once, the buttons overlap but is easily avoidable. Only bug I noticed so far is if you have researched the ice box and buy something to bring your BTC below the cost of it (150), then it says it's locked and needs research. However, if you are above 150, it goes back to normal and you can buy it as usual. Another bug seems that selling the clever cubes seems jank or the selling value is misrepresented (I think it only gives you 50).
