If all else fails, I've learned from the brief bit of game development I've had experience with that taking what you've learned from your projects into the next one is a great way to go about things!
If adding that combination effect proves difficult to code in or tampers too much with the balance of the game you're going for, I imagine making a game in the future with that concept in mind could be really fun too!
Either way, I really enjoyed what you have here with Tic Tactic and will be there the day it's fully released on Steam so I can play it right away!
