Writing this as i am playing: your game's initial look makes me wonder if anybody made a game using the theme as in "you're getting hotter/colder (in the treasure hunt meaning)". Anyway, back to the game! Really nice all around.
1. The fourth level was a bit difficult but i guess that's expected.
2. Got stuck at the third level with the freezer between the doors. It could not move so the doors are constantly closing. Maybe the doors could "blockable" and allow the blocking trolley to move or the indoors doors could be avoided.
3. Couldn't always keep up to the text speed and was able to pass all four levels. I wonder if could do the same without any text at all, apart from the item properties of course.
4. Really nice. The tiles were awesome!
Really enjoyed this overall, it was clear and concise. I would love to see snapping to tile, adjustable properties and maybe popups on the chosen items. Of course all of these would be asking too much of a week long jam. Very nice work!
