Here's the first screenshot of Spaze Invaders on-calc. Apologies for the quality, the colours don't show up very vibrantly as it's just a photo taken on my iPhone Currently the game loads up and initialises the game play screen as shown. The player can move from side to side and shoot the laser. Aliens don't do anything as of yet, but the shields/barriers function properly.

I'll be sure to post more shots as I make progress

Agreed, looking awesome

Its coming along quickly! With the sprite updating, I feel your pain! In Frogger I use one line to erase the game sprites, with Tunnel, I chose to leave in the 'artifact' to keep the speed up. I think speed is probably the most important aspect because there's so many people hating on the TI84+C assuming its slow (including me before I got it!). The game screen size is fine, you could fill up the border with stars or alien pics or match the graphics like the side panels on the arcade!

Just a quick update: I took a break from AB5 last night and jumped back over to this to make some progress. Aliens now do their side-to-side dance and make their way down the screen, and you can shoot them out of the sky with your trusty laser. Next up I'll implement the alien lasers, then loading a new level once all aliens are dead.

Seeing as it's hard for me to post any decent screenshots at this stage, I'll upload a demo version in the next few days for those that want to see how it looks on the calculator

A very simple demo can be downloaded here. Controls are the same as the original TI-83 version: arrows to move left and right, [2nd] to fire and [CLEAR] to quit.

It does sound pretty cool even though I have no CSE to try it.

yeah, too bad i don't have a CSE to try it out, would be too awesome
