I love the art, ambience, and sound. really solid concept with the plague and hot air balloon trading idea. Whoever made the art for this game did a fantastic job!
My only concern is that I tried to finish level 1, but the game bugged out on me every time I built the hot air balloon. The timer would stop, and I couldn’t restart the game unless I reset the whole browser. Hopefully that gets fixed, because the idea itself is really fun.
