Ok, i see what you haved try to do. I really like this kind of games where you have to figure out  how the game mechanics and the design works to pass a level. It's a nice puzzle platformer BUT:

Audio it's too repetitive.

You spawn, in level one, over spikes. That's BAD design. Spikes are spikes, are pointy are dangerous by common sense. You can't (even if you want to suggest that you going to need the spikes as a platform after) use spike as platforms and go against years of game design conventions. All you had to do was turning the spike sprite upside down when the spike fall so you have the flat part where you can jump and stay on.

That said i had fun playing it and figure out the levels.

Keep up the good work!

Nice little game, tough start though. maybe an easier intro then ramp up.

The game's concept is interesting, but the levels are hard, especially level 5, which I couldn't beat. I still had a good time playing it until I got to that level, though. 

To be honest, I found the game frustrating, mainly because of the awkward jump. Not to say that there weren't any good points, like the visuals and music, but it was confusing for me to get through.

It's a really nice platform, Level 5 it's really hard... I can't beat it, but was a really good entry... The intoduction of the mechanics it's nice and clever. Good work.

Nice, good work!

I played till level 5 and it took me 13 tries to pass the first level! Level designs are really good. And I love how gameplay is old school style. You just need to fail to learn what to do next. well done!
