Damn this is one of the best entries I've played!
I really like the artstyle, sfx, gameplay, feel etc...
I guess the only downside for me is that it doesnt fit the theme that well. And I can see it being a bit frustrating for most players.
As for the fixes: sometimes coins spawn right below platforms (like touching them) and it can be really hard to get those on dice4 for example. Also I think you can chop all the red stuff into categories from easiest to hardest and give it to player randomly in that "skill curve" order (well maybe you did but for me it seems that the clock arrow is one of the harder ones and I got it multiple times as my first one).
But anyway this is a very solid entry!
I kinda would like to hear your opinion on our game. Dont want to sound annoying, you just seem to have a solid grip on game design.
