I remember two online games I played between 2007/2008-2009 when I was like, 5. The first one had a blue gradient 3dish background. I really liked playing it and played it often. There was a red 2.5d ball and you had to draw white lines (similar to mspaint) with the mouse to get the ball to the end. I dont remember the number of levels though. The second game was Arctic themed and was kind of like Load Runner but with updated, low quality cartoony graphics similar to flash animated baby cartoons, the linux logo or Club Penguin. There were ice platforms with snow on the top and wooden ladders I could climb up and, to my knowledge, I remember multiple penguins and snowballs. I only remember playing it once in 2009 and to my knowledge, it was on the same site with the first game. The reason I remeber it is cuz in the middle of the game, our computer screen suddenly turned black. I later found that it was broken. I wish to find 'em cuz I wanna experience nostalgia.
I also remember that first game you described,the one where you draw the white line to guide the red ball. I don't remember the name,but one thing I can tell you is that I remember that the website I played it on was Gamershood.com . I'm searching around for it on there right now,it would be nice to find
