Cool arcade game! I really enjoyed this! Easy to pick up and play!

But I noticed that sometimes when jumping he wont shoot mid-air. Other times it works tho!

Nice! Not too easy, but it's great!

I'm trying too add 'score counter' - could you help me with this?
How did you figure it out
?

Best!

Hey here is the way I did the score: The last '00' of the score is built into the background. The first three digits are each 10 frame sprites that only occupy the upper left 8x8 corner of the sprite.

They have an 'on update' script that sets their animation frame based on the score. The animation frames roll over so for example the singles place is just set to the score and if it were 10 it would just display '0.' The tens place is set to the score divided by 10 etc. (It doesn't round up from 5 fortunately)

It may seem like I have too many sprites in a row because of the bullets but I only used one sprite for the bullets. One of the bullets is built into the background so the sprite actually moves over and conceals it when you have zero bullets.

I hope that helps!

Very challenging and fun!

Hey thanks for playing!
