Good for a quickie.
As soon as I saw the title screen the game seemed to be rather promising. But to my disappointment it wasn't as much fun as I expected it to be.
Art:
The art in the title screen and winning screen were cute. The (pixelated) art for the actual gameplay was simple yet nice to look at.
Music:
If you would've used the song just for the title screen it would've fit great. But using it for the actual gameplay didn't make the game enjoyable at all. It was too repetitive.
Programming:
The sticky controls added a slight difficulty to the game but it wasn't really fun. The delay of the controls made it hard for me go back and play the game once more. I've checked out some of Sam's programming in other games and I can say that he could've made way better than this. Also, what was the score for? You could've left it out completely since there wasn't a scoreboard or anything like that where the score would've been useful.
Concept:
The concept was cute and simple. Collecting mushrooms in a specified area while you can whip enemies and a "final" boss with your flamingo stick (or whatever it was).
The game was fun for some minutes but makes the player lose interest pretty fast. Sticky Controls. Repetitive Music. No power-ups or anything that could make the game more interesting. Nothing that could make the player crave for more (score, medals, etc).
But since this game was made in approximately 2-3 days I'll judge accordingly. Plus I'll leave out the music since it wasn't something you've made.
