There ARE supposed to be pets eventually, cloudslayer. A class based around summoning is too limited and waaaaay too complicated to code to be worth it.
I really don't see why this game deserves anything more than a 1/5. It's just another launch-n'-upgrade game. Next time, bring something new to the table.
I suppose it's good to know that Sandy Pants' difficulty thrives on the lack of decent troop control. We need individual troop control and better "blast radii". It's good to know where a bomb lands, but better to know whether or not you'll be damaged.
Why should I pay for this game? There are numerous other games like this that DON'T require purchases. I also recommend using ads rather than pay-to-use items.
Personally, I hate it when there's something obnoxious at the end when you die, such as the scientist's messages ("Learn your jumping", "Avoid Spikes", etc.). I'm sure it's kinda funny to read what he says, or watch the death sequence once or twice, but when you keep missing just one bulb, I'm sure mashing a button through his trollsy comment gets obnoxious, and the player then wants to track down and kill the scientist with a sawblade in his sleep. Games like this I generally rate 4/5 unless there's some way to restart right when you die.
