ChargingMoose's 1st Levelpack
ChargingMoose's 1st Levelpack (also known as ChargingMoose's BwB Level) contains one custom Keen 4 level, which is the first fan-made Galaxy level to be released on the Internet.
Since the only Galaxy level editor available at the time, TED5, is not compatible with the released versions of Commander Keen by default, ChargingMoose used a slightly modified TED5 in combination with a hex editor to create the level. This achievement got many people excited about the possibilities it adumbrated. The same month, some utilities got written to extract data from the Keen executables for TED5 to use, though it had yet to work out a reliable method of patching homemade levels back in so they could be used.
The level has Keen fall down into underground. Once he gets the blue gem, he has two options to complete the level: One leads to the exit, while the other requires meeting the Council Member (a red gem would also be needed for this case). There is a Lifewater Flask sitting right between two spikes, which requires pixel-perfect precision to get.
ChargingMoose's first level was featured in Buried in Oblivion, where it was edited to add some new graphical details along with a top section that has stone houses.
