it's fun but the custom characters are buggy as hell. half the time, the abilities for them work perfectly fine but sometimes the abilities just completely freaking break and it will mess up to where you can't add passive abilities to the base form turning into a bad time mode and you can no longer change your power stat. this is a big freaking problem because it completely ruins all of the extra modes for custom characters sometimes and it can be really irritating. other than that it's good.

Coming back to this, this game is better than ever. I've loved it ever since I first found it years ago, but I never expected such an upgrade! The new characters are amazing, and the custom character section is amazing! The only issue I see now is a few laggy areas (shop too) and there's quite an abundance in advertisements. Keep up the bug-crushing and happy new year!

I used to love this game, I then came back. Only to realize THERE ARE ADS EVERYWHERE!! I'll have more time watching ads than actually playing, I open the game, ad, I enter the store, ad, it's especially horrible in the genocide mod, at random times THERES AN AD AND YOU CAN'T EVEN HAVE THE OPTION TO TURN THEM OFF WITH A PAYMENT. If this game doesn't get rid of it's ad problem then it's unplayable

What’s new

Giant Update!!!
* Genocide Mode - battle against a giant number of bosses!
* Improved Skin Editor!
* A ton of new content!

Apologies for such a long delay. This was the most difficult and large-scale update I've ever made. It literally squeezed all the juice out of me. There won't be any more long breaks like this. Thank you for continuing to play the game!
