VENA (Viral Evolution: Nano Attack)

by Dakota - 48 Hour Compo Entry

There are a few bugs which I have been unable to solve after hours of attempts. The Enemies will disappear randomly but this doesn't happen too often. Similar to the problem I had last year its to do with screen coordinates which I still haven't solved yet.

Sound effect will from time to time drop out as I don't really have any idea how to use milkytracker properly to get the sound in the correct format (or the bullet noises over power everything).

The game may also be un-completable from time to time due to a Enemy not showing if there are not enemies left and a bullet coming down the screen from time to time you have got to the end.

Enough of the bugs

The game is fairly simple shoot the viral blob things and try to destroy them all.

There are 10 blobs in total and each can die 14 times before finally dying. As you kill them more and more they will evolve to become more powerful and more will be added.

I didn't include a bar or visual measurement for it but the power of your gun is effected by the amount of hits you take. collect the blue pickups to gain more damage.

Enjoy and don't the god awful music put you off playing it again.

Also if you have the opportunity test it on a real GameBoy

I have a jailbroken PSP running a gba emulator. I'll be sure to dust it off and give it a go on that.

Like you said, an indication of what the power-ups did would have been nice, but it is a fun game anyway. Kudos on making it for GBA!

For those that can't use VisualBoyAdvance because 'PowerPC applications are no longer supported', try BoycottAdvance

Firing up the game now!

I didn't understand the power-ups, but it was entertaining to play nevertheless. The graphics are great.

Good job on publishing as a gba game! The blue powerups were not that clear. I didnt finish the game. too hard for me :-)

I wasn't able to get it working on linux mint:

./boyca: error while loading shared libraries: cannot open shared object file: No such file or directory

A package for libc++6.2 wasn't readily available, installing 6.4 didn't satisfy it, and when I symlinked the newer lib to the older lib name, I got a symbol error.

A gameboy game, yeah ^^.

As others stated, more feedback was going on, shown in the game, would be nice (e.g. what the popups are used for).

I don't normal run linux and it was the only emulator I could find for linux.

It should work on any good GBA emulator so if the ones that I put in dont work just have a little look for another if you wish.

Cool platform choice. I haven't done anything with the game boy advance in a long time. I have a programmable cartridge, but I don't know if I have the software to program it anymore, or access to a machine with a parallel port to get it loaded; if I can get everything setup I'll give it a try.

I think it's really really really awesome that you made a game for Gameboy, props on that!

The game itself was rather fun, it's a solid shooter, although obviously it gets rather repetitive quickly, but I assume creating the game for gameboy ate up most of the time.

Actually, reading the description again, it does seem like the gameplay actually changes as enemies get tougher, although I can't say I've stuck around long enough to see things change. I think making the blobs evolve faster or make these changes happen faster would grip people more.

Overall, congrats on making a game for gameboy!

Always insta-props to people who make GBA games for Ludum Dare! I liked the graphics a lot, but the gameplay felt a bit repetitive.

Nice gameplay and musics, it's classic but well balanced, I like it !

Yeah they do change as you kill them more I think I may have set the Max Enemies a bit too high at 10 which means in total you have to kill 140 enemies (14 lives each)

I'm giving you credit for makeing GBA game. It's not best but is playable.

Wow, lookss and sounds great. Some more varied enemies would be good, or maybe a screen-clearing power up of some kind.

Very nice!

Wish there was a bar for the power :) More enemies woudl be nice.

I got this to run smoothly in linux with vba, but the sound was off, so I can't rate that.

vba --throttle 100 -4 VERA.gba

Aug 27, 2012 @ 6:25pm

Not sure if I didn't get far enough but some extra weapons or powerups would have been good, it seems like the enemies would have changed if I got further though? The controls felt good, really responsive.

The enemies never actually change sprite btw but they change attack patterns and spawning. I would have added a larger one but sadly its not a simple as adding a sprite sheet I have to draw it all out in graphicgal then in and create a pallet for it at the same time then into my convert to convert the bitmap into hex data which the GBA can ready. After that I have to create a sprite for it in GBA and copy over the sprite data into VRAM and thats all kinda for one frame.

I have eased the process for me but it still takes a long time. Next time I will be using OpenGL and Lua

Fun, it got challenging really fast, You should have instructions on how to run it though.

I love the fact that this was made for the gba!

A space shooter inside the body?...well, it could be in a battle like an infection and nanopharmacs, no? :)
This is a great contibution, i would love to make a GBA game, now it is easier for me.
Talking about the endless game, why the enemies cant hit you (collisions)? , it is supposed to evolve in any way?

You get nostalgia points for making me use an emulator again!
although the theme, as with many other games I've seen here, seems to be a space shooter with evolution painted on top. :(

Why the hell didn't you raised your hand when I was asking for retro games in the LD??? This is a very good game with good gfx and music - maybe you could have chose a somewhat less annoying sound for the gun.

I didn't programmed the Advance before but I do made things on the DMG and on the Color as well as on the DS. If I am remembering right then there was a limit of the amont of sprites you can use in a rasterline on the GB. I'm not sure if this is your problem here though.
