I never made it more than 10 seconds into the game despite about 50 attempts. The quality of the workmanship on the game looks very impressive but it desperately needs a much more gentler introduction phase so players who are trying it out for the first time can get their eye in. Alternatively a Sonic style one-hit and your lose your coins could alleviate this, because the precision on the timing required is so exact. I swear about 10% of the time I got killed despite not appearing to even hit anything.

That being said, I am not going to mark the game down just because I suck at it, and balancing is a fine art, especially when playing your own game - it is not as obvious when new players will find what you have practiced on forever hard.

Personally I would have the first 30 seconds of the game just revolve around jumping over the trash cans and the gaps, and then introduce the moving obstacles. It will allow players to establish a rhythm to the game more quickly, and then introduce the additional element of also having a dodge stuff.

It is too hard for me even on normal difficulty (well, like those retro games, so this is success I guess).
Inconvinient that it doen't work without installed .NET runtime (maybe it is the case only on my ancient Windows 7).

This gave me nostalgia, dude! It's good
