Take your time and have fun, tinygremlinqueen! The early access discount is pretty good though, so maybe buy it now and play it later? Because I'm afraid the price is going to gradually increase >_<
My friend was actually really nice and got it for me a couple days after I posted this comment! Trying to convince one more friend to get it now so we can all play together soon (He's going to get it but is a little busy)
Wow, I'm so happy for you! I hope you're having fun! It's best to play with friends because the Towers can be really hard. I'm playing single player, lv 50 and still haven't beaten the game x'D
