This is a greatidea for a challenge.
I originally was going to make something similar to Ceddo's (which is one of my personal favorites, along with the Junkie mockup by am_pm), and had the Kirby minigame as a backup, but they're now both taken.
Hmm... I think I'll do a variation of the Kirby game instead. It's even easily doable as a real game because the player and enemies just need two poses (sheathed and attacking.).
You press a button when DRAW appears, then immediately, the word COUNTER or EVADE appears at different intervals, so some double-tapping is needed if you want to survive.
The goal is to consume your enemy's life points.
Rarely, the word FINISHER appears after the COUNTER/EVADE and you have to tap again (which makes it a triple-tap) and finish off the enemy with one blow if successful.
If you tap the button without any on-screen instructions, you FLINCH and don't get a move the rest of the "attack phase".
Some of you might think it stupid that I'm already thinking it up even before the pixelling, but I just want to get some ideas down.
