May I suggest an option to automatically have the fast forward button on? It'll make the game much more fluent if I can have the fast forward button on by default instead of manually clicking it each time I start a level.
I am impressed by how awesome this game is. You guys did a phenomenal job creating one of the best games I've played on this site, and it had a bunch of unique and creative games tossed up. You have variety and all. Outside of a few minor spelling mistakes, this is really good fun. 5/5.
...So, I was at the second number pad, randomly mashing numbers. Bored, I decided to try internet meme numbers. I typed in "1337". Correct code. I win forever.
Very awesome game! Just a suggestion, but I think it'd be pretty handy to be able to refill your spike count. I'm a bit hesitant to use them later on in the game since you only get three. Maybe similar to how you can pick up ammo refills with the balloons? Just an idea, nonetheless. Also, Robot T-rex? Well played. 5/5.
Might I suggest for the sequel that there be an option added for skipping what upgrades you don't need (without penalty to your lifespan), to speed things up some? Cheers.
