The way you fight boss will determine how it will evolve and improve itself during the next encounter loop.

Eliminate red aliens to gain fire upgrades or different weapons... but doing so, these small enemies will be tougher to kill.

From a learning perspective

This game was made with the wonderful Pico-8 engine.
In this pico-8 source code you will find examples of:
- Cartridge data management : save/load scores and stats (dset/dget)
- Direct access to sprite/video memory : dynamically alter graphics when an enemy is hit (peek/poke/memcpy)
- Big sprite partially stretched (during title or game over screen)
To access to the source code you need to support by donating at least $1.99 USD.

- Inspired by the game Warning Forever -

Other references:
- Galaxian 
- Gradius (for "Option" powerups)

Thanks a lot for your kind words and for your donation !! :D


This game was a lot of fun to play! I liked the "chunky" pixelated art style, and the way the sound effects have a satisfying crunch to them. I also liked destroying the big baddies piece by piece, as it was a bit challenging and felt good to see them explode. This reminds me of some shoot-em-up games I used to play at a local arcade as a kid. Well done!


12,643 in ~5 minutes. Phew!

Hello again! Sorry it took me so long to get to your game but I gave it a go and really enjoyed it! I made a let's play of your game alongside another one here~


Thank you so much for playing! I'm glad you enjoyed firing at these bloops!😅
For your information, if you try to fill the screen with small aliens to maximise your score multiplier ("leeching" technique), it will become harder, as enemy fire rate may increase depending on the number of entities on screen... 😈


I'm glad you enjoyed it! Ah I did think that it would be harder for me just not in that way for some reason haha :D


This is awesome :3 


Hey! Played a bit of this on my channel. :D

Thanks a lot for playing! 😀
@3:14 Good looking boss ship 😂


Sorry it took a week to record, but thank you for the email! Really fun arcade game! I can definitly feel the similarities to older arcade game and I love that. The difficulty curve is pretty good, enemies are just tough enough once you get farther in. Really enjoyed it, good job! Might try again to see if I can get farther

Hey Cyberwolf! Don't worry for that!

I liked how the left wing evolved at 5:14 since you focused on the wings. 🤩
Many thanks for playing! 👍


That got craaaazy. Wow so many upgrades and bullets and OPTIONS FTW!


Made  a video


Thanks a lot for making this let's play video, and sorry for your arms and fingers! :p  ...And congrats for your 78k score till sector 15! Glad you enjoyed :)


I made it to level 6!!! Cool game. I just miss a bit of music but the blips and blops make the job ;)


Ton jeux est vraiment très très bien il m'a rappelée mon enfance quand je jouais a SpaceInvaders , Galaxian ou autre jeux du même type c'est vraiment énorme BRAVO


I took it upon myself to beat this game. I didn't beat it. But I did probably do better than anyone else who will ever play this game. As long as they don't get past level 7. 

Woah! :) Thanks for playing and for making this video!

Just a small tip if you want other boss parts arrangement: Try to destroy the wings first. The wings should grow if you do so (instead of the front).

ah you got a higher score than me i only got to 20k at level 9


Very enjoyable shmup to play! It's very classic in style, but has some unusual things, like the sounds effects which sound a bit different somehow. Nice amount of different upgrades to the cannon.

If you'd be interested, we'd like to see this game in our annual contest, the Game Development World Championship!
