Hi guys after a long break i decided to any% speedrun but as i said i forgot the mechanics any advices will be appreciated thanks for helping out

Good to hear you are coming back to the game! DEMO is the top guy to advise right now (he is in a league of his own) but for the moment the main things to remember are:

1. Damaging enemies temporarily allows you to pass through them unharmed, so don't bother killing most things, just hit them once and walk through them;
2. Strategise where you are going to accept taking damage, the optimal route for each level will usually mean finishing with only one heart;
3. Practise sword swiping and shooting the magic bolt in quick combination, for quick kills on enemies.

thanks drgrumble the first advice is very important i think i have watched DEMO's any% (very cool guy by the way) trying to learn something

also i would like to thank Sleepwalker_92 for being a good moderator instead of me xd

Nice to see you comming back to the game! I think that I can't explain the main mechanics better than @drgrumble did. The sword attack to avoid collision is undoubtedly the trick you'll need most in the game. Although this trick can be done to all enemies, it doesn't maje you avoid the damage of their attacks. Hence, the green balls damage you, the spikes of the spiny monster damage you, the hammer of the white monster damage you, etc. Apart from that, everything else is learn the most optimal path and practice it a lot to learn the mechanics. Btw my current WR was done for the Mobile Marathon, so it is fully commented, so maybe I say some tips in there. Also I recommend you not starting with Any% but with Acts, they are shorter and are really helpful to practice
