In case people come in a call it fake

I won't call it fake - there are nice techniques to avoid a lot of sprites per line... the game is for MSX2 isn't it? Is it on BASIC? (The lines and the way text is cleared made think it is...). I specially like how the range of towers is shown with just a couple of sprites ;)
Just one question: can you add more towers/upgrade the ones on screen after the attack starts?
Anyway, it looks cool... but as I said, just a few enemies on screen. Real TD games have lots of them, running at different speeds, so enemies can pass ahead of others. Hope this "engine" can do this sort of thing :)

No I can't :D I didn't write it.
The game is in ML and this is only stage 1
hi all again,
just to say i am doing some quick&dirty trials in turbo basic.
And i got good speed moving 7 creatures and 4 towers firing at the same time , i guess it can go up to 12 creatures and 4 or 5 towers in turbo basic and still decent speed.
this is on a msx2+ 3.5Mhz in screen4 with all animations are sprite 8x8 based.
not so long listing like 45 lines in basic.
i think i can post the code by the next few days : to have a basic tower defense game in less than 100 lines in basic . anyone intersted in doing gfx/new levels or more programming in basic.

That sounds great!
Anyway, do remember that, whether you'll use the internal MB 1.4 replayer or some external one for the music, that this will slow down things for sure, and certainly on a level you might want to calculate beforehand.
On the other hand, if you're doing things with HW sprites, you save a lot of VRAM/CPU time I guess.
