I was so excited to buy but I had too much food at lunch and I slept lol!
I just got this beauty and I am so deeply, deeply thankful!
Hooray! :D
This is just lovely!
It controls perfectly and the graphics are very nice and readable.
Love the bricks.
There is just an issue I noted that in the end of the level in Puzzle Bobble you just get the type of balls that are left on the screen (if only green and blue are left you will get either a green or blue as next ball or something similar).
In your version you can get any ball color always so it is quite hard to finish the level.
As a nice to have I wish it had music but also like this it is a very nice game that I will play with pleasure on my real C64 :D
I've tried your game and it is indeed a nice implementation!
If will try to give you two small suggestions to make it imho nicer:
I've found a nice / easy / well done timer API here:
