(What is)  Worth mentioning was that the glue pudding, (which was) one of the traditional foods of (in) the Winter Solstice, tasted (was) so delicious that I even burnt my tongue because I ate it too quickly. Everyone felt happy yesterday night. Though we couldn't stay with our families, we still felt happy and warm in this Winter Solstice.:)
By the way, all of us had a lot of fun during the game "truth or dare".O(∩_∩)O~

Your article is  basically very good, so not a lot of amendments required. Be careful to leave a gap after commas and full stops. We usually show the significant words in the title with initial capitals. You were writing in the past tense and in your fourth sentence, quite correctly, used past tense verbs - was, had - but used 'want' which is present tense, so I have changed it to 'wanted'. You used the phrase 'to go home' twice in this sentence so the second reference can be deleted. The only other thing worth mentioning is the sentence regarding the 'glue pudding' which turned into a 'sticky mess'.....haha... if you excuse the pun. It is quite a long sentence and you used the verbs...is (what is), was (that), was (which was), was (so delicious) - so it sounded very clumsy and unnatural. I have suggested removing the initial words 'what is' and just amending it slightly so it is more cohesive. 

Sounds like a good time was had by all. Happy Winter Solstice !

Very well written, Elle!  I just made some minor corrections through your sentences.  Be careful to use spacing between sentences.  Also, when expressing a time period, many times it is better to use the word "during."  I included a few examples in my correction.  You're doing very well writing paragraphs.  Keep up the good work.  :)
