You should really hotkey the reset button to the "R" key
And maybe add an option so you can go to the next level faster
I didn't find any errors, other than Steve falling to the lava and being able to play afterwards xD
Anyway, it isn't bad but it isn't good either, it just looks like a reskin of another game, but with less gameplay

It's a well done game, but I don't really find the topic interesting

The graphics are fine but the gameplay is bad and the game is not interesting, there are many games like this one
