Good game! the addition of costumes makes this game a metroidvania :)
However it looks like there are some bugs. These are what I've found:
1. TVON doesn't give any candy after completing his quest
2. Collecting Candies beyond 105 will cause candy counter to turn into Candy 0/5 and key image disappear. Key can still be used even though the image disappear
3. After the bug #2 above, accessing Home is impossible. Chat can touch it without any response
I know Home arrow is how to end the game cause I accidentally touched it before
Speaking of key, Spooky Blvd does have gate but it doesn't seem to require any key
That being said, it's a good metroidvania :). The secret path is really tough. I wish it has better reward at the end but it's rewarding to find it though :)
