All points i agree with. I planned to have collectables but jam limitations. an hook aim is very unforgiving.
I did lots of optimizations like a day worth. but GDScript is not a very fast language too loop over a million objects. I want to do Spatial Hashing to speed it up, not a feasible to thing to do in a 4 days. PC version plays much better than web version tho.
I hope you enjoyed it. i will update it after the jam is over.
