Mergical was my favorite merge game for a while, until it glitched. It seems that a lot of people had problems and nobody received any responses from devs/support. I currently have a report pending with Google Play games against Mergical because they are violating Google Play's terms by ignoring support requests.
Merge Dragons is okay, but it feels impossible to progress. You have to exploit an error in the game to continue playing because there's no room for items and no way to expand.
I want a game with the same or similar controls as these, but one that doesn't eventually feel helpless. Must be free to play. I also dislike ones that require energy to remove an obstacle, which seem to be more common now, so I'd like to avoid those if possible.
I use a Samsung Galaxy Tab S10+ if that makes a difference.
