This one was... Well, quite addictive ! The music was well chosen, the graphics were nicely made, and I loved the poker-themed atmosphere.
I stopped at wave 23, seeing that there was no more new units and that they just had no chance of going further than the first line. Imo, the game could use a bit more balance, to maybe make it a bit harder. An increasing amount of HP/wave for the units might be a solution.
However, I really felt I could get easily addicted and just playing it on my phone casually. Good job !
