You misunderstood what I meant. I meant due to how the controls work and to get a decent amount of gems, you have to jump alot and sometimes you go to jump just as you land and instead of jumping again you end up doing some fail stomp move.
In my opinion, the stomp would be better suited on the down key as this way you won't accidentally end up performing it instead of a jump.
Sorry, I should have made my point clearer the 1st time round.
The difficulty balancing is a bit off. The game starts off easy, gets hard just before the middle point, becomes easy again just after the middle and by the end its ridiculously easy.
If you make the badge require that you need to mine the COre again, then atleast make it respawn on re-entering a world, as it sucks that I have to start again to get the achievement.
Either that or make the achievement so that the COre has to be missing to complete it.
The time based in-game achievements suck ass, watching a walkthrough would ruin the game, but playing the level to death to improve my time would be boring.
Directed mainly at the level 15 achievement, I have completed the game and gain all the upgrades, why would I want to continuously farm past the games end.
