Question about Cake Mania 2, PC version - are there more levels? - please help...?

I'm not sure what level I'm on, but it appears to be the last one in the Moon building. I start the level with $2999 for purchases. I upgrade the middle oven for $2000 and it leaves me with $999. I play the level and have succeeded in completing the level and collecting the "Time Bender" award 3 times (this is NOT easy!!!), but when I try to continue to what I'm thinking will be the next level, I'm back with $2999, without the oven upgrade, and it appears that I just keep playing the same level over and over. Is this the end of the game? Is there a secret at this point, or maybe a glich in the game program? I am playing on Windows XP and don't appear to be having any other problems with the game. The characters in this level (I don't know the correct names) are: the purple Alien and the Clown-Looking guy or alien dressed in white with the freaky eyes, the Biker-looking dude, the Cop, the Granny with the baby, and the Samurai. Once in a while a guy who looks like an actor or something pops in. I've complete this level three times now (and collected the Time-Bender Award) over the past two days and my right hand and wrist just can't take any more. Please help!!!
