App description: Erika, a pilot from Angels Corp was tasked with retrieving Project I.R.I.S from a secret lab located West of Borneo Island. Upon approaching however, Erika's fighter jet was hit by an incoming enemy attack. By some miracle, Erika survived the crash but her ordeal was far from over ...

Your Objectives

- The enemies you are about to face wants to destroy the secret lab. Do whatever it takes to prevent that from happening!

- Use the two beam gates to destroy any incoming enemies. If they managed to get past the gates, use the area-of-effect 'Pulse' to clear them off.

- Manage your energy wisely. You will most likely to fail if you just keep the beam gates activated.

- Automated supply units will appear at random times, trying to reach the lab. They give random perks (like extra energy) so try your best not to destroy them.

Hi everyone,

Dylestorm here and I'm a solo indie game dev. The game's design, coding and graphics are done by me (with a bit of help from my wife on the character design). The game's sound effects and music however, are store bought.

I.R.I.S - Def Op is a simple defense game that contains a small amount of strategy elements (energy management, when to use 'Pulse Bomb'). It is relatively short and can be completed within a day. I do plan to update this game with new mechanics and gameplay styles in the near future but for now, I just wanted to get the core game out for people to try.

Let me know what you think of it. Any feedback is very much appreciated. Thanks!

Update: version 1.0.6 changes on the #5 post

Nice simple game. Easy to get into. Can be quite tense towards the end of each level. Some of the ships are sneaky, and protecting supply ships is challenging. Best thing is that the mechanics are original; not a clone of everything else. Erika looks kind of mean; wouldn't want to get on the wrong side of her. Ads don't work and produce an error message.

Thanks for the nice feedback Stronsay I do notice the ads are kind of hit or miss. Will take another look at the codes and see what I can fix.

Hi everyone. Def-Op : Codename I.R.I.S (previously known as I.R.I.S - DefOp) has been updated to version 1.0.6. Since its first release, I have been tweaking and making improvements to the game. Here's a quick summary of the core changes.

- Lengthy tutorial cutscene has been removed, replaced with a 3 page summary with some comic style images. This allows the player to get into the game faster.

- Improved main menu with properly labeled buttons. This makes navigating around much easier.

- Tweaked the game controls. They should feel much more responsive now. Previously there was a bug that randomly causes the right beam gate to not activate.

- Redrawn Erika's (the main protagonist) in-game portrait. The original art didn't really fit in well.

- Under-the-hood code optimizations. My original game codes were pretty messy and all over the place.

Do give this game a try if you haven't yet. Any feedback is very much appreciated.
