I'll preface this by saying the only time I've played something in this genre was a short try of something another DD. So my problems are probably because of inexperience with genre conventions. Played through three battles, skipped a lot of dialogue though.
- I remember seeing your characters ages ago, you've improved immensely.
- Most backgrounds could probably be run through a filter to make them look more "animey".
- Right click to go back, like from the options menu feels weird to me. Esc doesn't go back.
- The controls in general feel pretty awkward, can't use mouse in battles?
- The "Move cursor" tooltip doesn't actually show you which buttons they are, I assumed it was the arrow keys at first glance.
- I wonder if the battles would look nicer if the camera was tilted more, maybe if you could even control it yourself a bit.
- I don't really get when units can attack, retaliate, double attack - seems arbitrary. For example I'd have a unit start diagonally next to an enemy and I couldn't attack, but if I move into another diagonal position he could attack. I thought I got how ranged units worked for a while, attack two squares, but then they can't anyway at times, etc. Most of the time I'd just click around to see what could be done from what square.
- Played on a laptop so middle mouse button was a bit annoying.
- No way to quit out of the game in the middle of a battle?
But as I said, I think most the control issues are with me not having played similar games. The battles were fun though, and I didn't encounter any bugs as far as I know. So I hope you keep working on it!
