Game completed at 100%. I was missing like three items when I finished the last level. Luckily they were 2 CDs hidden in the most recondit places possibles of the last levels, and one hat similarly hidden there.

Up to level 10 full cleared, all minigame-related achievements gotten. (1h53m)
--------------------------------
Up to level 19 out of 35. I'm missing one chip collectible and whle I can pinpoint it to a few specific levels, I don't know where it is. :(

Played the first four levels with all collectibles + the first minigame which admittedly took around 30 minutes to beat under a minute. Oh well.
