I think there's some great potential here! This is the first game in the jam that I've seen use a dialogue system (that I've played so far) so that was a nice touch! Also being able to buy upgrades to unlock new areas was something I enjoyed!
It was short, however it felt like it is in a place that a lot of levels could be added on!
Only real issue I had was that I almost couldn't find where you were supposed to go once you got all the upgrades. Luckily I jumped off into the void on the right and was able to find it! That might be part of the design, so I can't complain much!
The jump felt a little off as well, but I got used to it after a minute or two so I'm not including that as a complaint, especially because the ability to climb up edges was very forgiving!
Overall I think there is some big potential here! Keep after it!
