Custom Blocks:
In the sonic event there were many custom blocks in many of the maps. Custom blocks make a more unique experience than the normal blocks. The inclusion of them made the sonic event so much better. Hive could use more custom blocks in future maps. I’m not saying everything should be custom blocks but to just have a nice mix of them the maps.
However, this might just be nostalgia and me trying to experience some form of the past again. It might also be more worth it to work on gameplay than the looks, but I would like to see some other opinions on my suggestion.
