Purchased this yesterday after seeing a reTweet by Vinny from Freeze64 about this. I cant believe I let this one pass me by on release. But made up for that now. Purchased and played. Very impressed. I will be talking about this on this months Pixel Gaiden podcast and will recommend that people come and give this a shot. Love the design and presentation.
At first the dynamic for down and fire for shield was annoying me and kept wasting them. But it's a good way to activate it when you need it rather than hitting a key on the keyboard. Could you maybe make it for two button sticks and give an option in a later version so you could activate with the second button maybe?
Thats my only thing and it's minor, does not detract from the enjoyment and this is now one of my go-to shooters on the C64.
Good to see the NTSC support and will be trying it out on my NTSC C128 to see the speed difference!
Great work :) - Tim from the Pixel Gaiden podcast
