Yesterday I promised an update, I’m doing it this early since I’m a bit tired so there’ll be little progress.
So, for now the level of the enemies to spawn will be “controlled” by the amount of time you’ve been playing (e.g. you play for 2 minutes and it starts spawning Enemy 2 mixed with Enemy 1).
As for the “flying” speed and shot cadence, maybe a mix of time and score. Still playing with ideas about this.
Also, as I have said before, this game will be really simple and short. This means 3 or 4 enemy types and one boss, overall, maybe 15-20 minutes of gameplay, if that much.
See you next time.
