The art and the theme are great, but there is a lot to improve in terms of game-play.
Firstly, the pace of the game is too fast. New players are not given the time to learn the game: Not only that all cards appear right from the beginning, as OddMess pointed out, but also that the constant influx of monsters deny any time to read the cards, devise plans, and play strategically. Even as I paused the game by opening the menu, the menu itself blocked the card zoom-ins.
Secondly, card balance is rather off, particularly:
- Khepri's Spear is too weak. As an early building (it cannot be upgraded) it is only ~1/3 better than Horus's Archery in DPS but double in price.
- Heket's Obelisk is next to unusable on its own. For every enemy the tower(s) kill, the player will have to remove a Curse - that was all I could do the only time I tried using it, and I had to take care not to play Spells accidentally too. Even if there is a Thot Consecration, it is going to be buried in tens of Curses once the deck reshuffle.
- Amon-Ra's Tower is a terrible starting choice and is not that strong late game that can persuade me to include it in my already rolling deck.
I beat normal difficulty full health with Apophis's Archery Tower alone, plus a few +dmg spells from Tauoret, and Horus's Reload. I did not find any incentive to mix Towers.
But then again, nice ideas there. Keep up the good work!
