First, thanks a lot for this huge feedback, this is a lot of help for us!
-> Actually, we were working on pulling mechanics during the gamejam, but scrapped it because it took too long to finish in 60 hours.
This will definitely be in the full version!
-> Yeah, the trampoline bug is one of the worst one's still in the game, but this should be fixed soon! (Did you find the easter egg where you needed the bug to find it? ;D)
-> Really cool ideas for making the game special! We didn't manage to finish more than just the pack theme yet, as this was our first game ever, but we'll definitely do more than this in a full version and probably even make use of some of your ideas ;D
-> Yeah, I also noticed the color/background issues you mentioned, especially small packages that 'hide' between all the background packages. Probably the parallax scrolling would also be more effective with more defined background parts.
Thanks again for all the positive feedback and especially thanks for the time you took for this, as this will help us quite a lot for a full version!
