Really fun. I miss these kinds of games, reminds me lego flash games from the good old days.
i skipped a box few levels before and still passed. On the big climb i managed to collect a lot before i ran out of parts. Mostly have trouble on the stacked 6 boxes on the top as i managed to access the top ones but didn' get the rest and the upper right corner loot room as i ran out of parts. Safely brought them down by dropping onto the zipline.
And the big climb just loops to the first level? Was the amount i got enough or...?
A good game but no polishing up the balance and no end screen.
