DRJ Nice looking C64-action game teaching me Dutch language!

DRJ (Doctor Junior is it?), Radarsoft, 1985, Commodore 64 version
Many games from Radarsoft were translated in other languages. For some reason, the only version of this game I have ever seen comes with the original Dutch language. This made it quite challenging for me to learn it at first, but eventually this became my favorite Radarsoft game.
Those who are not familiar with DRJ at all may be interested watching some of the videos below....?

My videos include cheat POKEs for the games. POKEs require a reset switch. If you don't have a reset switch in your Commodore 64, you may be interested checking my instruction video, how to build one:

I met him at a local C64 enthusiasts meeting where he talked a little bit about his game developing experience in those days. Mostly about how his games would sell for about two weeks and then they would be pirated.

Radarsoft had some very nice titles, but often with very awful music renditions. Shame really, as some games would be a lot better with an original soundtrack behind it.

DRJ is John Vanderaart, he made some really cool C64 games (i loved 'Hopeless') and had a very humorous way of writing articles for Dutch C64 magazine 'Dossier Commodore'. One of my heroes in the C64 age. @faqmanvanderaart

Seemed similar to grotten van oberon but that was C. Kramer.
