Really neat game here!
The art is really cool and the levels arent too difficult, i really like how many features you've neatly put into those five levels. Really like the pacing of new Traps and other constructions too. :>
Though of all the upsides the music i think was a tiny bit too into your face for me at least, the rest of the game hits just the spot for me (also fish get leggies lol, pretty funny ;) )
Thumbs up!
