Depending on the situation I'd use the phrasing "delayed" or "delayed indefinitely".
And as @lol56lol already suggested, adding the 'cause' would help others to get a better idea of what to expect in the future. Not only concerning "lolipop simulater" but also when it come to your potential future works.
Also: Isn't your "Boom"* submission "lolipop simulater"?
