Tested on my A1200 with and without the 030/50 active. Played identically on both configs, that is perfectly well but it didn't feel that smooth though- I don't think the low-res of the player sprite helped but I realise that can be fixed easily. The actual scrolling seemed consistent and steady without any perceiptle variance inthe frames per sec it ran at.
Since there is already a Flappy bIrd clone on the Amiga you could change it to clone Splashy Fish instead ;-) Also, might be cool if you put a little frame around the playfield to look like a smartphone
