Fun: I couldn't beat the last level and constantly got stuck on walls, but the gameplay from the other levels was fun.
Theme: Being able to switch in the air was fun, but also there was a glitch where when you switch and you and another robot hit the roof at the same time sometimes you won't die
Twist: You didn't use the twist at all.
Overall a fun game, but there are quite a lot of bugs. This is to be expected for a game made in 3 days, so no worries :)
Also, I can't prove anything, but I swear I've seen that dog drawing before, and it doesn't match the rest of the game's art. Did you forget to credit someone?
