Sorry that was juvenile.
Actually good question which I haven’t really thought about,
have been doing healthy / outdoorsy things on the weekends over the summer so haven’t been putting much hours in
but am intending to go into hermit game dev mode soon.
Still, I can only work on it maybe 5 hours on a weekends
(so when I say month then that = about 20 hours )
So, trying to be optimistic then
There is no great gameplay plan,
it will be just shoot things to get points and pick-ups so don’t have to worry about too much there.
Draw 1 x 1st stage tiled background with 3 transitions. (starting work on that now) (1 month)
At least 5 different type small / medium enemies (1 month)
1st Boss system with 1st boss graphics (2 months)
Ship graphics and pickups – (1 month)
Hud graphics – (1 month)
Interstage graphics – (1 month)
Menu system with options and graphics. – (2 months)
Sound effects and music (no idea. Could be months)
.…wish you hadn’t asked that question now….
and enemy patterns (1 month)
and bullet patterns and some sort of bullet pattern engine...... ( 2 months)
terrible question man,,,terrible
.....wish I hadn't thought about it now.....
so to answer your questions demo 14-16 months......
