A player can make a raise on their own bet(happened after an opponent folded). While 3 raises is the max per round, the initial bet shouldn't be counted as a raise. Flushes also seem to be more common than they ought to be. Opponents bet/raise too often and don't fold enough.
It might be slower than a real game. Opponents shouldn't automatically fold if they cannot call; that is, they need side pots. It's possible, when opponents cannot post the blinds, that they have negative funds...and then fold when it's their turn again. The betting's slightly confusing, since it doesn't reset each round(to lead out betting on the turn should be a bet of 8). Since the amount you've put in the pot already is irrelevant, I'd suggest clearing the 'bet' amounts, and start at 4/8, clearing it after every round.
Tank spawn location needs fixed.
There's no way to quit/return to menu.
Creativity and dynamics are lacking--add levels, power-ups, options, different enemies, lives.
Vertical movement could be an option.
It's a decent start, but needs much more work.
If you charge a wave of crusaders as the onset of each battle, the enemy's slots get blocked. It doesn't wait for the slot to become unblocked, either, so, as it tries to send more troops, it wastes them. The same thing happens if the enemy has shrines or vipers blocking the slot, as well.
