Here's a thread for any minigame you've created. A good place to test your game idea too.

I'll start with my game, where you control two players at once. Since they start at different directions, they will always travel in different direction! You must reach both white tiles at the same time to complete the game.

Thats just a cool idea! Really well done.

Cool game, but try making them turn at 90 degree angles. It will be easier.

Here's my next minigame: defense. The difference to most tower defense games is that you need to actually aim the towers with your mouse.

How to play:
-Mouse button 2 enables shooting
-Mouse button 1 creates towers

wow. cool minigame. :D i like

Twitchfactor

(Posted 2008) [#7]

I like the mini-game idea. Unfortunately, the Defense game doesn't seem to work properly. I can place 2 towers, make them shoot and that's it. No enemies ever spawn.

I still like the idea of rapid-prototyping or minigames, though.

nawi	(Posted 2008) [#8]

Do you have a ridiculously high uptime so that Millisecs() returns negative numbers? I can't figure out any other reason for that bug.

Twitchfactor

(Posted 2008) [#9]

Yeah, just checked millisecs() time at the start of the game and it's somethin like -1560744888.

BTW, the other game's cool, even though my expectation was that I would slide along the walls and not go through them.

How long did it take you to write these?

nawi	(Posted 2008) [#10]

Not that long.
