Lemmings 2: The Tribes (Prototype)

More of an unrealeased game rather than a prototype.
It's identical to released Gameboy version, with all the same animation glitches, level design and gameplay.

I personally enjoy this sequel much more than the original Lemmings and the 8-bit version is quite faithful to the original Amiga version.

However, some of the 8-bit exclusive levels felt too easy and can be completed without moving the camera at all. Funniest example could be at 04:15:34 and it made me wonder if there's more lemmings to find in levels just like in Lemmings 3, since the number of Lemmmings is presented as "08", which could mean the 8 Lemmings is just a start number and there is more Lemmings to find and rescue.

Or it could be a programming error just like using archer skill while other Lemming is using attractor skill!

All 8 Lemmings saved on each tribe.

Gamegear version also exist. Instead of being just of cropped Mastersystem port, it has more color depht and "let's go" jingle at the level selector screen.
