I took the plunge on Tides of Time k owing full well how feature-poor it is, but thinking the .99 might be worth it. Having played it, it is even more regrettable for me me now that Portal didn’t bother to flesh out the multiplayer because the game is very competent and fun. There are a few things I would change - card art, for example, needs to be much more prominent. That said, the game plays smoothly and I like the visuals that Portal added; much like Through the Ages, your cards are represented by buildings on your map and glowing lines connect between them when there are points to be scored. I think it works visually. There isn’t much single player to speak of other than quick battles, but there are challenges that earn you currency that you can use to unlock and customize your profile avatar. It might be worth the .99 if it is still in sale if you’re in the mood for a good, quick little single-player puzzle, but the lack of modes is completely woeful. In fact, the menu only is two options - quick play or hot seat. I actually think Portal was on the right track and then just pulled up exceedingly short.
