Thanks for answering!
I can definitly add layout settings and try to make it so that you can use other keyboard leyouts.
Actually, you can even program the keys position-wise, so that you do not have to care for rebinding them. ;) This is very simple (at least, on some APIs I know, but I guess this should be simple for pretty much all frameworks/engines) and generic.
Having a timer for the catplants would be hard to make,
Oh; wouldn’t it be straightforward to merely have a local counter for each one?
(By the way, since votes are now enabled for everyone, I will come back here once I am done with my 3-long default rating queue. :) And I uploaded my little humble Game Boy test, I think I will expand it in the future!)
PS: just discovered that the public votes were deactivated (which I think is a good thing, in fact)… Maybe I will try entering my semi-prototype; not sure.
