A pretty ok little time waster, this is one of those type of cheapo games suitable for when waiting for another game or large update to finish installing. Although, it is closer to what should be a $1-2(or even FREE, considering "DLC" asking prices) price rather than $5. It's not like there was even any real time, money or skill invested into the development of these type of games.
Anyway...
The game plays fine enough, however does still suffer a few flaws.
Absorbing opponents can be a little wonky. They even sometimes teleport before you can finish them off.
The 'Katamri' ability's functionality is extremely buggy.
For Achievement hunters/completionists, the Achievements for dying 10 & 50 times could be a bit of an annoying grind if you already fully upgraded the magnet & crowd size prior.
