Great game with a neat concept and execution.
The visuals and sound effects are very cool and I love the music. It would have been cool to add a little bit more contrast on the projectiles of the pogo because aside of the first kind of projectile, it was a little difficult to see them. With Godot you could have tried the PointLight2D to quickly add little bit more dynamic style on them. ;-)
I think the important feature which is missing is a little mention of the game controls. I found super late that I could shoot with the weapons, I almost got frustrated because it was super hard to kill enemy only by bouncing on them with the pogo. :’D
