I'm going to go against the grain and say that the game was of appropriate length. Considering how simple the gameplay is, I don't think length is required. If the game left me wanting more due to really fun gameplay or controls and upgrades, I'd want it to be longer, but this game is fun and simple, and short as a result.
Reviews for "Johnny Upgrade"
Pretty impressive game. 4.5 Stars. Although at first I was shocked when I blew up after 3 seconds.......
great game, really glitchy though.
Pretty good game, liked quite a few elements of it. The concept in general is very reminiscent of games such as ZHP: Unlosing Ranger Vs. DarkDeath EvilMan.
This game is lots of fun, and I love the first play through, yknow, where you die immediately XD
But my favorite part about it is probably the high ceiling on upgrading. So long as you keep up the coin gathering, the game is fairly easy and not very frustrating. A very well rounded game with steady reward that keeps the player interested. Good work.
