I haven't finished it yet but it's very cool so far.
Edit: I finished it and collected all crystals.
The game is really cool, game has very strong style that made me really enjoy the game.
-Music was really good.
-I love the art style.
-I love the announcer when collecting power crystals or gaining new powers.
-Pause menu is awesome (It could be cooler if metallic man would slightly change pose depending on what you selected on the menu)
But there are some things that I would improve/add.
-On the first level I didn't notice that platform you need to jump on to get the first ability. I got it by getting the worm to launch me to it.
-I would make the first ability and attack rotate you to the direction of the walk input (it's sometimes a bit annoying when you realize that you forgot to rotate to the right direction and end up missing the jump)
-I don't know if its a but or not but there is no sound when hitting the enemies I would add some (its always better if player get feedback from successful action)
-Also combat could be a bit better, maybe some 3 hit combo or getting slightly launched up or just stoping you from falling when hitting an enemy in the air would be cool.
-make that you can destroy the statue on the second level.
- I would love if there was a button that would make metallic man strike a random pose. (I would love to do that to the rhythm of music)
-I would love to see more of this game overall.
Maybe a cutscene when entering new level for the first time and see metal men interacting with some characters or commenting about the place, give him a rival like plasma man or stardust woman that wants to collect all the cool crystals for themself and have a bossfight at the end or something idk, I just would love to see more of this game.
