Hello, Mom? Hi, I might be home a bit late, so go ahead and eat dinner without me. No, I'm not with a girl. I'm running away from T-Rexs, Lava, and a large Tidal Wave.All right, I love you. Yup, bye.
I think there should be a way to convert resources. Example: You have 52,000 Putty, and you have 200,000 Twigs, and you're trying to upgrade your Sniper Tower to Level 4. So, you should be able to convert your 52,000 Putty into 50,000 Twigs, therefore having enough Twigs to upgrade.
This is the way I sometimes feel. I love the music, and especially the story line. I love games like these. Please make more. If you don't, thank you for making this one.
