@antti-haavikko Oh my god. You are so professional. 1. I agree that it is weird to allowed player to climb anywhere. 2. I also agree that the condition that player could place down a package is too accurate. This could be annoying. 3. Indeed, the guide system is not reasonable. We didn't inform that the player should deliver the box to the house. 4. We use several ready made assets and draw some by ourselves(such as character) the house is from other project 5. I totally agree that it is easy for player to feel tedious after running left and right just to deliver the package. I think the puzzle design should be blame. I suggest the non-linear level design and smaller map with more intersting puzzle could be better. 6. Slime box problem. It is actually a conflict between object attribute design and programme design. I should be blame for this problem. When I programme the destination, I use collider trigger to determine whether a package touches the destination. But the problem occurs when you put down the package, because it would detect the collider near you to prevent you putting a box inside something. And the destination is also a collider so you can not place a package in the destiantion directly. Most of boxes have gravity force to ensure that they could touch the trigger. Slime box didn't function that way. It would stick to the background without falling down, whcih cause the problem you mentioned. I would change the way program determine the conditon.
Anyway, thank u for your precious feedback. It is really happy to get so much feedback for the first time of this game jam.
