Oh, I'm impressed with this game. It uses very simple mechanics, but thanks to good effects and easy player victories, it leaves a very good impression. The current version already has enough content to keep me engaged. The cheap upgrades are also welcome.
The fireworks seemed the most useless to me. I got the hang of the Sonic Trap the best. Although, I mostly focused on upgrading character's attack, so I easily one punch enemies at any range.
