This game is REALLY tough, quite an exercise for my hand lol, tho you have used premade assets I got to say you did a great job handling the visuals.
Maybe enemies should move slower? It's wayyyy too hard for me at this current state, maybe there could be more mechanics like being able to stun the guys who shoot bullets and all or a potion that protects frog from one hit for a minute or so.
Either way good job on this game :)
