Cool game with amazing graphics and a very fitting song :D. Had fun helping to get rid of grandfathers debt.
Some minor things which could be improved / added:
- I had the feeling that I go quite often the same puzzles, but not sure.
- Maybe the puzzles could get more difficult and not as random as they appear now. I got difficult ones at the beginning and then suddenly very simple ones.
- Sometimes I have overseen the small part lying next to the tool (as it had the same color). Maybe placing it a bit lower would have helped.
Overall a very cool game!
