After finishing playing the Halloween demo, all I can say :
It's a pretty good demo build! I like the decorations and Snick's friend's in here and unfortunately there are some flaws in this demo build:
1# The Moveset: Moveset is pretty interesting, but it's kinda not easy to get used to it and it's pretty hard to understand it even it has tutorial, it doesn't explain the new moveset Snick's as for his Manual, Speaking of the Manual. It's kinda disappointed it didn't changed, it would've been cool to introduce some Snick's friend's in Manual and gave them a bit information about them and explaining tips on the Snick's moveset
And last flaw will be #2 The Achievements: Honestly after even I've completed everything the build has to offer... Expect the achievements. Unfortunately since the shop have been removed. You cannot finishing the two achievements, and I don't know why you didn't remove these two achievements in this build? And also after S ranking all the levels (including the Snick.EXE challenge) there is a bug of dialogue between shader basically the dialogue won't not change probably due to not the finishing the cowboys achievements,
And that's all what I have to say!
I'll rate it: 7.8/10 Not bad
