Haha. I loved the wordplay there. Duck. Tape.
Yes, sometimes jumping was ignored (especially when taped up on the wall) but other than that, cool mechanics.
The biggest issue I had was with dialogue. It says "continue" yet I cannot click on it. So I pressed space, and my duck jumped and it messed up the text. Only afterwards I realized it is F to continue. That could've been said in the textbox too. Also some of the text went off screen.
Otherwise a beautiful game with nice colors and characters, and the flappy bird animations were great. :) I am unable to download actual executables from other people onto my game development machine, so I appreciate browsergames a lot! Thank you.
