Hi idah6, thanks a lot for the write up, Im glad that you decided to loose your comment virginity on my game :D
Source code is only required for combo LD and I participated in the jam. I was restricted by the time but I also think the popups would work better than text in the level, but it was the quicker way. The same is with the coin model, my friend who was doing some of the assets gave up after first day so I went with the quickest way to do collectable - the sphere.
The level names are brilliant idea and I will surely add it in the next update. Basically I agree with all your points except of one - the map. I quite like the exploration factor of the game, but I agree it can get frustrating. Maybe adding sound when you are near a coin is way to go. (similar to Fortnite chests).
Thanks again for the feedback, I will update the game as soon as I can. If you want to participate in testing (If I decide to continue developing the game to commercial release) you can join my discord (https://discord.gg/QShCdg) so we can talk more frequently. Also If you are interested, I made a video about development of this game and on what went wrong :D
