A retro platformer where you reach each successive exit until you surmount a final challenge. Minor puzzle elements, alternate routes, a simple but powerful item-combining system.
Tools are strewn across the levels, and can be activated simultaneously to 'combine' them temporarily, or combined/dismantled semi-permanently to make things easier, leading to ever more complicated combinations.
Food works in much the same way. For example: combine a sprig of fern with meat for seasoned meats.
