Is it worth Full price -> No.
75% discount/ Key-shops-> Maybe.

The game itself is okay, Graphics are amazing pixel art. Sound effects and music are okay too. There's even small puzzles including arm-gadget.

What my problem is with this game are battles 1vs2 or 1vs3, also economy system is a huge mess, and there's barely 100+ monsters in the roster (counting in evolutions), which is not much.
It's basically 40ish monsters + evolutions, which is a shame for a monster collecting game.
That's my 3 main issues with this game that made me decide to NOT RECOMMEND.

It's a strong 5/10 game, could be better. Developers announced Remaster of this game which sounds like a port from Mobile version of the game for the same or increased price. And game itself looks basically the same... so "Remaster" is a bit overstatement here.
