Really enjoyed the visuals including the art, trails, menu, and characters, Music was lovely to listen to as well as the sound effects. Animations are clean looking. I enjoy the young-mid-young system. Locking some of the mechanics make certain scenarios quite challenging, Shooting, jumping, and dashing works well. when they would be easy if all mechanics were unlocked. Midlife Crisis fits the theme extremely well.
I think the health regenerates too quick. It's quite confusing where to go once you reach the dash section (figure 1). Some upward hill terrain has weird collision (figure 2). Found a bug when holding S and moving in this section (figure 3).
An extra animation for falling would be a nice touch. Adding particles to the projectiles would remove the placeholder feeling of the asset.
Overall, great work!

Yes, the health regeneration was something we didn't have time to balance, as we played it safe and overdid it to reduce player frustration and maintain the game's pace.
The other points you made will be noted for implementation after the game Jam voting is done, as there are some updates we already have waiting.
Thanks for playing, and we appreciate you taking the time to provide feedback.
