I realise the roll of the die somehow influences how it behaves, but it's not explained how or why or what we are supposed to do with that information. I just ignored the change in properties and was able to complete the game without much difficulty.
Maybe the game could have been improved with some art or sound. Brown on blue is not really pretty.
One property, "charge" is just useless. I never found a situation where not using full charge would have been useful, or where hitting a specific charge would be necessary. Waiting for the jump to charge is boring and adding to that wait time just slows the game down without any benefit.
It's a working game, and for someone's first game it's not a bad effort.
