Loved the art style, the crocodile is very cute!
The concept is fun, though I feel like the different elements don't quite fit in a satisfying way. I honestly had the most fun when I just left the sidebar as is and played strategically carefully chosing my targets according to damage numbers. But then sometimes the reload time would be very high so I would just run around waiting and then try to kill as many enemies as possible without paying attention to the numbers. On the other hand, fiddling with the sidebar would be ok at the beginning, but as the the game got harder there just isn't enough time so I would just start ignoring it
In general, I quite enjoyed the game, though it would be nice for the different elements to be more balanced
Nice work!
