i bet it would be helpful to loads of people =)
is it something that could only be adapted to 8*8 monochrome on windows, though?

A beta version with the first 2 levels of the game is now available here:

If anyone finds any bugs, I'd be most appreciative if they're mentioned here (or to me via email) so that I can rectify them

Works great for me from Doors (both versions). Maybe it was a different problem?

I haven't played too far yet, but it's great. The explosion effects feel really nice

* shmibs tried it out today, and it crashed on me as soon as i hit new game.

is there any reason why this wouldn't work with doors?

Well that's no good - as far as I know it should be Doors compatible. Were you using the Ion or MirageOS version of the game? I'll suss this out. I'm possibly going to compile as Doors-specific build of the game anyway, so I'll be ensuring that it is Doors compatible.
EDIT: I just tested on my TI-84+BE running DoorsCS7 and the MirageOS build of AB5 and it worked fine for me. If you have anymore info you can share on the crash you encountered, that would be great

Thanks!

Hmm, does it work on a Ti-84+SE? Would love to play this.

I don't see why not Link. I've been testing it plenty on my TI-84+BE so there shouldn't be any difference that I'm aware of.

Vid is looking awesome! Can't wait to see the finished result

that's a lot of time there (as compiled for different shells)
I downloaded and hope i can try out soon

I still remember when Tower Assault came out (back when i checked ticalc everyday) and then (was updated into?) Final Assault. Now i can't remember if it was an update to Tower Assault or a whole new program... I never played the 8x8 scrolling games, but even those look fun! Thunderbirds are go! was really cool, too, even though i remember it being a bit short (and rather large on my ti83 ). The graphics were what impressed me the most. Anyway, this new version looks and feels so much more polished than the others, there are only two things that i feel are still lagging behind:
1. The texts (like the introduction) on a blank screen are really an eyesore compared to the rest of the game, with its beautiful levels, animations, explosions, bullets, etc. It feels like pretty much every other game coming out in the late 90s/early 00s. Just like the Megaman 83 intro or Phoenix's UI!
2. The computer system also lacks a little something. It doesn't FEEL like you are on a computer, though i think the cursor does look nice.

I'd be surprised if Alien Breed weren't featured on ticalc
