I love this game! The only improvement that I would suggest is to allow the ability to tailor the robot after upgrades are purchased, e.g., arm length.
controls/movement seems to lag and stick, particularly on the level with the tv screen. i have to press down each time i do a new movement to stop the character from continuing the initial keystroke command. frustrating. Other than that, very nice concept.
Pros: fun, simple little game... I like that your money doesn't get taken away when you die; Cons: and I find the upgrades page unnecessarily confusing and I don't like that the “upgrade weapons” feature defaults to bullet every time you return to the page. On multiple occasions, I’ve upgraded one thing, thinking I’m upgrading another...perhaps an undo option? Or a confirm button?
