(I played v7 which seems to be the latest jam version.)
A very cute, coherent and polished game! From the blooming flowers over the hovered option in the main menu to the cruncy leaf sound that plays when you pick up something to move it, you can tell a lot of love and effort has been put into 8U6. Also, it's got 40 levels and a level editor (what?!) - that's HUGE! I also appreciated the auto-save feature that shows which levels have been completed in the menu.
I found the music to be charming and a good fit for the game, but maybe a little bit repetitive. I think having one track per 10 levels would be a good amount, to keep things varied. The only other feedback I could give would be nitpicks, such as putting the next level button above the close button, instead of below.
Possible bugs:
- From the main menu, clicking "Custom" and then "cancel" on the file open dialog causes an empty level to be loaded and then shown as completed.
- I couldn't beat 3-7 so skipped ahead. After beating the others I was able to access level 4-1. I quit to go back to the menu to try and go for 3-7 again but then I couldn't access 4-1 from the menu. This might be by design (i.e., it appears when all 30 of the previous levels are beaten but I'm not sure).
All-in-all a great experience and one of my favourites from the jam so far!
