I love the fiendish difficulty that suddenly springs on you once you have gotten the hang of how to play.
you reactions have to be spot on and you have to plan one moment ahead in order to come out on top.
the difficulty, while infuriating, never seems unfair and if you make a mistake you know that it was your fault, but at the same time you can always see how to correct your error after the fact, or before the fact with just a little planning.
very fun game... and a bit addictive, I'll freely admit.
my two criticisms of the game;
1. The Environment
vary the environmental aesthetics a bit more (environmental mechanics were amazing up to the point that I have played through). let's see some dim crystal caverns or dark (yet visible) misty chambers. varying colours? maybe and add a bit the the reward segment at stages end (lockehorn's dancing is cute, but add a bit more sparkle... some charm)
2. the abilities
the one thing that I kept thinking was " it would be so awesome if I could jump over over the ice-block (not direction jumping mind you, just a 'hop in place' sort of move)" it would open up opportunities to let the block pass under you harmlessly if you can get the timing right and start pushing from the other side to add more momentum in a shorter time frame and maybe also if you 'hop' with exceptional timing you could 'ride' the block and get a 'ride bonus' until the block hit a solid object, knocking you off the ride bonus (numerical value floating in the air) would then burst into coins and/or gems that you could then collect (similar to when a 'coin pot' is smashed) depending on the magnitude of the 'ride' bonus. maybe also rewards for near misses and 'hopping' over the 'snow bunnies'.
over all great concept, sweet execution.
am still playing right now!
