Pros:
- Colour choice is nice and balanced
- Consistent visuals, particle effects aren't obnoxious and add nice little atmosphere
- Effective minimalist animations
- Humorous dialogue / intro
Cons:
- 150 denarii is a bit steep to grind in normal play. On my first playthrough I dodge-rolled past all the enemies and later found out I kited them all to the man on the beach which was very convenient, but if I hadn't it'd be a lot of walking around.
- Mouse-based menus in a game controlled by keyboard is a bit bothersome. More importantly the game seemingly cannot be unpaused.
Here & There
The dialogue boxes being on a timer feels restrictive, and the joke in-game is okay but at the same time I probably would have preferred having control and dropping the joke. The tiles sometimes don't line up, which I assume is a Unity thing, and as such a grid will flash onscreen for a frame or two in certain situations which is a tad jarring. You can kick or attack and roll at the same time, I'm not sure if this is a bad thing, but locking the different movement/attack things so they're exclusive from one another might be better. Theme adherence is kinda there: It's a sequel to a thing that also makes it silly, but the mechanics do not seem to explore anything new, ie there's nothing to do in the game that might not have just happened in the actual 300 movie in terms of actions, such as kicks and slashes and cool rolling.
This is your first game iirc and I think you should be proud (this is far better than my first game). It's a tight little experience that is consistent throughout and is bereft of any horrendous bugs, so you're well on your way to making some good stuff. I'm sure you've learned plenty so that your next game will be even better. Keep it up!
