I love the crocodile sprite, but the rest of the art style is a little less cohesive, some things have outlines, other don't the detail levels are vastly different etc. I would maybe spread the effort across all the sprites so it's a bit more cohesive. I liked the upgrades, but it was a little bit confusing how the towers worked. In the end it's a nice little game with a bunch of mechanics in 48 hours so something to be proud of and I hoped you learnt a lot :) (For others, you have to press the green button to start a wave of ants)
