Hi, I just tried out your games SuperTed and Smurf Rescue. Nice work!
Both worked fine on my A2000. SuperTed loaded and exited cleanly from Workbench. Smurf Rescue would not load from workbench (stopped at a grey screen after a second or so of disk activity), but ran fine when executed without Startup-Sequence. I noticed other Backbone games sometimes act the same way... I think it's a Backbone thing.
As others have said the bottom of the screen on both was cut off on NTSC systems. I didn't mess around with this very much to try to find any work-arounds. I did try the NTSC version of Smurf Rescue, the entire screen was visible just the panel was missing, like you said in your description.
Gameplay-wise the slow rate of fire in SuperTed kind of did it in for me. I didn't like it very much, then again I don't have any kind of nostalgia attachment to this theme I'm sure others do. I really enjoyed gameplay of Smurf Rescue though, but again as someone else said... the inertia could use some work. It was confusing figuring out how far to jump and not over-jump, or slide around. The graphics were great though and I loved your use of samples, I can definitely see myself playing this one more in the future, thanks again!
Now to catch up on my backlog of other Amiga programs I wanted to try out, LOL.
