You should make the size, and which fish you can eat, more consistent. It is a bit annoying to die when attempting to eat some that are clearly smaller than you.
I really like the effect of growing heavier and shorter jumps, when you have full energy. It is an interesting new idea that you have to balance between too little and too much life. Other than that the game lacks some other element... I didn't feel like playing it more than a couple of times.
People asking for reset button: If you change the level it resets.
It is a nice puzzle game, good job on your first! It could be improved in some ways: WASD or arrows as a lot of people have said already. Other than that you might build a menu for choosing levels, and unlocking them. It might add a bit more sense of accomplisment to the game.
Too easy to be a challenge. Need to be more use for tower suchs as slow. I would like to see different tower types, such as splash or area effect. I really like the flame thrower. Great effect in speeding up enemies.
I got stuck dead in a check point... Every time I reload it start (or really doesn't) the same place, just flashing different screens, and no means to interact. need a possibility to start all over.
