Its good, but gets boring pretty quickly.
it is inposubl for rocks to fly.
The game was really fun, however the difficulty was really off.
The game was boring at first, because your so slow and getting used to swinging the hammer, but over time you get used to it and it becomes fun changing the different elements to destroy the ones coming after you.
The graphics look really creative and I liked how the elements had different personalities and some were happy, angry, ect.
The controls overall handled pretty well, but I found that swinging the hammer had some issues. I'd try to swing it sometimes and it would just putter back and forth instead of swinging one way or the other. This is probably just an issue with sensitivity.
One of the only major cons I can think of was getting all those upgrades, but I never really even came close to having to use them until the final boss, which almost killed me. I went from having 3/4ths of my health always to dying once and beating it the second try with less than 1/4th. If the difficulty were scaled better, the upgrades would seem more rewarding.
Other than those couple cons, you made yourself a great game.
Good work, friend.
Apart from the last boss being far easier than the others, I have no complaints.
