Woah I am first earner of a medal from a five years old game :o
I did not know how many points it was but I got disappointed when I got it and saw it was only 50 points. Playing through 500 levels takes about 35 hours and even if it is not hard it is more time consuming than other 100 pointers. The levels get longer and longer and the last levels are about seven minutes long. Halfway through should be around level 360. In the end I started with 65 coins.
Bad:
Two major bugs:
Sometimes when I lose a coin I continue to lose coins. Once every time I land and continuosly from a while after I land. It gets fixed when I start the level again. This makes the later levels harder because they are longer. It is usually better to try to keep your coins instead of try to take risky ones.
Sometimes, but rarely, I do a sudden turn without moving the mouse. It is usually downwards so I cannot help but collide until I have lost every coin.
Minor bugs:
Buying new coins costs the price + ten if you have that much. Otherwise it costs the price + whatever coins you have left, so buying the 31st coin for 300 while having 304 coins costs you 304 coins.
It is possible to fly. Yes, really. It is a rare bug, but I found it quite fun. You can get over the obstacles but you have to stay above blue floor. You teleport to the floor when you jump.
It is possible to get through obstacles sometimes. Usually when you hit the obstacle by the obstacle moving and not you.
Other minuses:
It scrolls to the left which I find annoying.
Upgrading agility makes the game harder. A tip to other players: Leave it be at level 1!
The game could be fun at first but it quickly becomes boring. I muted the sounds and listened to music in another tab to make it more interesting.
It needs a pause button.
I got annoyed at the moving obstacles at first, but after a while I learned how to approach them in the best way and they were not annoying anymore.
Good:
Nice color palette.
It saves! It is really nice so I can take breaks and get the last two medals.
A mute button exists.
It had me hooked for roughly 30 hours. Cudos for that.
The obstacles move in the same way if you try the level again. I do not know how this was made possible, but it makes it so you can predict their exact movement the next time you try.
The API timeout is rather long for a Unity game. Should be an hour at least. Some users have complained about the medals not sending again, so it could be good to quit and play another time for level 100 and 500.
