I watched and saw you checked out my submission Arcade Merged! It was so informative watching a player experience it with no influences from the developer; a few things I wish I made more clear:
- Your combo increases for every enemy you defeat
- Your combo resets anytime you allow an enemy to get off screen (so going really fast makes it very hard to get a high combo)
- The higher your combo; the more powerful your ship gets
- You can defeat a "Pongle" board by destroying a single paddle and having a ball touch the far end; or destroy all the balls on the board
I should have improved level 1 to make these mechanics clearer to the player! Lessons learned for sure, I am glad you mentioned having fun playing it!
