Interesting puzzle mechanics and nice pixel art, pretty difficult on the last level but it was fun trying to path my way through. More mechanics/levels and some audio (honestly think just some UI clicks could suffice) would round it out a lot but it's a good base.
(I did find a funny exploit though :P Once you have 8 pals, you can "bunny hop" the 7-elevens to reach the end. Basically, place A then B, sell A, place A further ahead, sell B etc. Would need to ensure the 7-eleven "chain" from Daps links to Lost)
