This was so delightfully silly - the premise of turtles eating guns itself is funny, and while the execution was a little rough, the game felt decidedly retro.
UI elements reminded me of the kind of thing you'd see before the late 2000s, where UI design was the wild west, with the UI feeling as much a part of the game as the character models. The controls felt weird, though, but the spin factor of the turtle meant your strategy was to wade into the fray and turt it up.
Audio was really solid - I feel like some good music'd really tie it all together, but the announcement voice lines and such really fit the vibe. It meshed really well together in the end.
Not too shabby an arcade shooter game.
