My thoughts about this game:
+ Game looks amazing, unique style. Fluid and cool animations too. Great use of colors. The screenshots don't do it justice. The snappiness and responsiveness of this turn-based game puts many platformers to shame.
+ Fun to figure out for a few hours
- Difficulty is bumpy. First 60 levels are generally very easy and casual including the bosses. This will encourage the player to play faster and not think too much since it's possible to recover from mistakes. Past that there are easy levels, but also some particular levels where a mistake will very quickly end your run.
- No saving. You only keep unlocked levels and characters when quitting. This sucks, especially because grinding the easy levels gives extra lives and powerups.
-There's a bunch of rubbish, unhelpful powerups and characters. Potion identification is a boring mechanic borrowed from traditional roguelike games and it doesn't make the game more interesting here either.
Mixing puzzle mechanics with turn-based combat is probably very hard. This game tried and kind of failed in that it's less fun/interesting the more I play it. But it's still a pretty cool game.
