Pretty fun game from the hour or so i spent playing it. The levels increase in difficulty once the animals start appearing (especially a certain elephant) which makes the game pretty fun. The introduction of disappearing pegs add an extra challenge where you need to time your shot to avoid hitting the peg and missing your shot completely.
However, if possible for some future improvements i think adding a level select would be nice to be able to replay certain levels and to be able to play where you left off.
Another idea could be adding a way to see the trajectory of your shots before you shoot. (up until the first bounce is fine in my opinion)
Adjusting the barrel hitbox as right now it is pretty lenient with the bounces.
Overall i give Pegs of Glory a 9/10 and hope to see others enjoy the life of Gigus Chaddus.
