I really enjoyed the game. the ways the coins work as both your health and action counter. it made it fun to play the game again and try to jump less and not get hit.
I didn’t get the doors. The first run I did I made it to the end with 184 coins without using the doors. Then I tried to use them in the next run and they just didn’t seem worth it to me. They might be more fun for people who are not as experienced with platformers giving them a way to skip a level they struggle with and finish the game. They are just not for me.
The fact you can’t move in the air made the platforming more challenging and made a lot of sense theoretically since you are a goblin trying to carry way too much gold.
I like the short story blurb at the start. It helps sell the game and the setting, making me more invested right off the bat. I might try to do something similar in one of my future jam games.
Good job :) very impressive for one of your first jams especially a 3 day one.
