This game is amazing. Here are some truly unique sections.
- Completing the last "number" level may seem like the end of the game, but there are a LOT more levels left.
- The Low Power Tunnels will cut off the music if the power runs out. Truly creepy.
- The "T" levels are the hardest I've seen so far. (Spoiler incoming) There are only 7 T levels, for those who are curious.
- The box storage area brings back the 3d platforming Run 2 had. Good times.
The game is great, and a sense of accomplishment comes when you complete all the main levels. However, there is one level that made me lose my sanity for the day. It's level T-3. The jumps are so random that you'll overshoot the jumps or fall short.
After you beat the LittleGiant cup the trainer of Warlord will challenge you occasionally. If you accept his challenge it will take you to a monster battle screen where the game will be stuck. You will have to refresh it to continue. So don't accept the challenge!

Same advice as always: try a different character. I recommend the lizard in this case.
