This was a fun puzzle game. I think the main issues are ones of UI/UX. It can be hard to tell what's going on a lot of the time. The swap action button isn't clear if it means "currently Moving" or "click this button to go into Move mode" - and if I'm understanding it right (which I might not be), it's also bugged in that it doesn't always show the correct currently selected unit's action (Convert/Attack/Poke). It can also be a bit hard to distinguish what team each unit is on. If you fail a level there's no way to restart. And finally, the sound effects are a bit loud compared to the music.
This all said, the actual puzzles (up to level 4; I accidentally messed that one up despite just about having the solution, and after being booted to the home screen didn't feel like playing the same few puzzles again) are really cool, and I love the concept of "fantasy siege as puzzle game" and how all the different units interact and have distinct roles that lead to mechanically interesting puzzles.
