Awesome idea. it could use more units though.
So far this is the best way to increase typing speed.
However, there is a glitch, re-playing levels will unlock all episodes one by one. Playing the first level when the final level is unlocked will send me to the ending screen, for instance. Might wanna fix that.
This was an enjoyable game overall, but it really had no challenge to it at all. I literally beat the entire thing without upgrading any of my equipment or buying anything. I would up the challenge if I were you for the next one.
Pretty fun, but kinda short. More upgrades would've been nice, specifically the ability to upgrade each individual unit.
fun on a bun!
