Charging $2.99 for a game that's already halfway done feels weird, but it's a great fun game on the whole.
Try to remember that this is personal opinion and that always varies person to person. This is based on my personal experience.
I bought the full game and while it is fun, is can sometimes be rather unfair; almost unplayable in some cases For instance, I will find a sword or shield behind a creature that is nearly impossible to obtain. In one particular instance I was in mid-game levels. I gathered all of the strength and defense items throughout the levels (at great cost to health due to my lacking said shield) and spent all of my gold on power only to find out that if I attempted to gain the shield, I'd lose well over 1k health; causing unneeded and exceptional difficulty later on. This has happened a few times in my ~10 play-through's.
Also, there's the issue where the advertised player levels are extremely limited and/or unfinished. The site advertises "Over 20 player made levels" and you'll soon learn that this is a flat out lie. There are maybe 5 total that are even remotely worth playing (not counting the developer level.) I can't really blame the player base for this as the editor is ridiculous. The icons are tiny, the tiles limited (I really wanted access to grass and those mountain tiles I saw in the beginning of the main story) and even though scripting isn't needed, the process to put in "Events" is, to me, tedious and not very user friendly. And this is even if it loads properly. I tried just now and it took two times just to load.
The game just feels rushed and/or unfinished in some aspects.
Even though my review is somewhat negative, I'd still recommend the game. It's a fun time killer.
I bought the full game for $0.99 for Google Play, yet can't play the full version here. Seems kinda lame to have all these medals you can't earn cause you can get full version on the site.
Good game, good game.
A joke for that price. Good game though.
