Tech Invaders 5 - SierraKen - 08-11-2024
Hi all,
It feels great to be programming again. Some of you might remember this Space Invaders / Galaga type game I made a few years ago called Tech Invaders. Today I decided to spruce it up and make it go faster, therefore more fun to play. I added one or two other tweaks also to make it more enjoyable. As with before, there's 5 boss aliens and I'm pretty sure that if you beat all 5 bosses, it starts over again, with no end to the game. And like before, it makes the "toptentech.txt" file for the Top Ten scores. Enjoy!

RE: Tech Invaders 5 - grymmjack - 08-11-2024
This is really cool @SierraKen
I see strange ghosting - is this desired? Or is my display just garbage or a setup issue?
Thanks for sharing!
RE: Tech Invaders 5 - bplus - 08-11-2024
Yes, had me hooked playing the game for awhile. Welcome back!
RE: Tech Invaders 5 - SierraKen - 08-11-2024
Thanks guys!
grymmjack, yes that ghosting is intentional, nothing wrong with your system.
Thanks bplus, feels great.
RE: Tech Invaders 5 - TerryRitchie - 08-11-2024
Nice start to a game. Keep going with it.
RE: Tech Invaders 5 - Dav - 08-12-2024
Hi @SierraKen! Welcome back - you were missed.
Nice playing little game. Hope you keep going with it.
