Thanks. This way I could play some levels, but even then I needed to click multiple times on next level. Played two funny once, however the you are fired timer is quite harsh. In the third level I played after reloading, there was a violet block shooting at me when I got close, stunning me. How do you get past this block? You can not jump to avoid the projectile as there are some blocks above you.
Thanks for playing ! Actually the levels are randomly picked so I don't precisely see what level you are talking about but as you may have seen, few levels are indeed not finishable. I guess you could try jumping lower (by rapidly releasing the jump button). Concerning the "next level" button, you are a level cleaner you need to wait for players to die :) (or just press F).
