I can't jump and need to buy upgrade? That's fine. Only 10th coin fell on my side of the map? That's bad game design, my friend. Tweak randomness a bit or unlock jump ability from the start. The whole location is dull. I don't see any reason to upgrade my jump only to able to reach 2 small blocks at the edge. The first coin fell on one of them after 3 minutes of gameplay. Make level more interesting. Add more platforms maybe.
