Hi,
I present you my game named Spooky Catch, winner of the Makeroid Halloween contest.
However, this is an alpha version: this means that there could be a lot of bugs. You can report them on my bug tracker: https://apps.maicol07.tk/bugify (Registration is in italian, use Google Translator.

Description
Capture the frightening creatures and defeat the boss! Halloween is the best time for a monstrous revolution… Fermal and save the world!
Story:
A group of monsters are attacking your city, with the intention of carrying out a world revolution!
A courageous man will try to face them, defeat them, find out who lies behind this evil plan and save the world! Will you be enough powerful to beat them?
Actually, only the first level is available and I’m trying to fix bug that the level doesn’t end until you lose… 
Sorry for that…
