I just wonder what an earth is happening while I'm playing...(!?!?!?)
It seems like my keyboard commands kind of "lag", when there is plenty os animated objects in the same level. For example if there is lot of treasures to pick up, when animated score points float in the air after picking those up or when there is about 10 different enemies possibly half of them shooting projectiles, THEN this happens:
I have button pressed down (for example "left"-button, when I'm moving left) and when I lift my finger from the button, Igor still keeps running left!!!

I've killed myself about 20% of time because of this "bug" or whatever it is.
This son of a

*¤%$# ruins my ability to advance further than 6x levels, because there starts to be more and more enemies!!! It is EXTREMELY FRUSTRATING to play, because I cannot predict, when Igor is going to keep moving the direction I pressed second ago. This only leads to instant deaths and point losses (missed big crystals and nice objects many many times, because Igor decided to drop down to the next level...)
What's wrong with this? Is this only an issue of my computer being too slow? (Shouldn't be) Is there something wrong with my internet? (Shouldn't be either) I checked that during this bug, frame rate where almost 40fps.
