I tried and I did, but...

Hello everyone!
This is my second LD jam. Last time I participated in a team as a programmer. But this time I decided to go alone and prove to myself that I can do all aspects of the game so that in the end it will be something fun.
I am generally happy with the result, but... I would like to finish the game a little after the jam and would be very happy to get more feedback.

At this point, I have already collected some feedback and outlined a list of fixes:
- Some training period is needed at the beginning. I am thinking of making something like a zero level, which will be available once and then transition to the main game.
- It will be necessary to make dying less annoying by visualizing progress on the defeat screen. And perhaps add some metaprogression, in addition to opening new upgrades.
- I think it is worthwhile to better signal the opening of new upgrades.
- Add a few more upgrade options to remove the need for the same ones to drop (since this is currently done due to a small pool)
- Change the music to a more dynamic one and replace the sound of volume change.
- Make a faster progression of mechanics changes (for example, add obstacles with a more obvious change in behavior to the second stage).
- Perhaps it’s worth changing the visuals towards something darker, but I’m still thinking about this. If anything on this list seems questionable to you, feel free to write about it.
