Hmm....I dunno, probably just my PC but I can't even play the Slender level without terrible lag. Sorry, but just not enough here to hold my interest for long...the yeti level was probably the best, as the water taxi just ended up getting stuck on EVERYTHING and the Slender level lagged massively. I think this was done in great spirit and you should definitely cheer, however! I like that for the Yeti level, he says "no time to explain" and turns out it was because of an avalanche, haha.
I liked the spooky lighting in Slender, hated the lag and weak music.
Swampthing is the funniest, but I didn't like that the cab stuck to everything.
I liked the gamplay in Yeti, but not the repetitive aspects of it.
out of 10...
gfx - 6.5 (not bad, needs anti-aliasing bad tho)
sfx - 6 (kinda boring background ambiance)
design - 7 (very funny, but lacks 'quality' toggle)
gameplay - 5.5 (things get "stuck", bad lag)
overall, this truly defines the spirit of gamejam and deserves to have won based on that alone. Looking forward to future games!
