Hello all, for those who have played my game already, thank you so much, your comments were very helpful! With your comments I have tweaked a few things:

• Your character can now double jump. No more getting easily stuck!
• There are now arrows indicating you the next falling block. It let's you have a little head start for the next block!
• For the 4K screen users, I have now made the game window resize-able, full-screen is also supported!

Once again, feel free to try it out, I'm looking forward to be hearing more reviews from all of you!
