Secret of Tree Tactics
I just thought I might make a basic guide for some tactics in passing some of the higher levels in Secret of Tree. Please add your own tactics for any levels I haven't added or even improve my tactics, they are by no means 100% effective. There are some level designs which I can never pass, so if anyone has strategies for levels I haven't added please post.
These are only the levels I saw today so I will add more as I see them if this post receives a positive response.
I use my Angelo and Lava, so all dragon shooting angles should be covered. Crystal and Rocco may have different tactics seeing as how they can freeze/stun opponents. Leshy should be reasonably similar but the piranha plant attack could open up some interesting strategies.

In this level slide down the hill where you will be safe from enemy fire. As the two right dragons shoot they should probably kill the one on the left. You should use your time while safe to build your rage. If you have Angelo you can time it right to power yourself up before your enemies break through and have extra strength. The two remaining dragons should be reasonably easy to take down.

Walk down into the gap. If any of your enemies are grenade throwers you should take them out first, ice throwers probably arent such a threat because their ice drop is blocked by the roof. Otherwise if you can handle a few hits target the middle dragon, try to knock them back a little, which should change their angle to hit the bottom enemy. The top dragon will normally hit the bottom one regardless. The bottom dragon will normally hit you and cause some damage to the ground you are standing on (watch out you dont fall). Take out what remains of the bottom dragon, which should probably only require one attack. Finally kill the top. Often the ground behind some dragons will be destroyed, feel free to knock them off the ledge.
