Thanks for playing!
Yeah, since both the bullet frogs and the laser frogs, these ones could use a bit of an extra warning. It is curious because, during beta testing, my friend was questioning why he was losing lives, and it was because, when the frog was in the laser line, as soon as the laser was created, the player was immediately hitted, the life lost, and the laser destroyed. So, I ended up playing with the sprites and masks to allow the player understand why he lost a life.
In general, my idea for playing the game was 'when you see a phrobo, avoid that line because you don't know what kind of attack it does'. But yeah, maybe a small inoffensive dotted line at the beginning, before shooting the full laser, might be helpful.
About limiting the range, I will have to think better about that, since I don't have an opinion for now!
