Awesome! Best for those who remember these games!
Excellent recreation of old hand held Tiger-brand-like games from back in the early 90's.
The attention to detail used is impressive. Using unlit icons to decorate the screen combined with the sharp annoying music that even includes a classic "mute" button really brings me back to dumping hours into games like this.
As for the complaints over proper or more instruction, I don't think they are merited considering the goal of this retro game. These games never had any instructions back in the day. The only thing you had was the button layout and trial-and-error to figure out how to actually PLAY the game. It was a challenge that I found exciting (though frustrating) but ultimately rewarding. This sense of frustration, accomplishment, and mystery is just lost on new generations of gamers.
In my opinion, the fact that you've managed to recreate that retro sense of frustration in figuring the controls out brings you a well deserved higher score rather than a lower one.
Bonus points for including a mute button too.
I would definitely enjoy seeing you make more games like this!
