Thank You for playing our game! I completely agree: the tool system needed more time to be fleshed out.
The end goal was to feature multiple tools with different movement mechanics and statistics, which player needed to master as each crate is necessary for survival - but also bestows a random weapon. We wanted the player to carefully consider whether they want to took the risk of skipping a crate to keep their weapon of choice or whether they are fine with giving up their tool in order for guaranteed survival.
In reality, due to time constraints only two tools were implemented and even they were not very thought-out, so apologies for that!
Thank You once again for trying our game, it made our day! :D
