Pocky and Rocky Reshrined: Max Power
This is a tough game and I prefer Max Power over Power Max lol. I do feel the stickers and this theme are worth the price of admission though it does have flaws in unlocks.
For some tips: 1) Focus on 1 color so you get this mode to make the first level easier (extra easy mode needs 3000 coins to unlock so forget an easier trip).
2) Your close range shots can reflect enemy fire.
3) Become adept at timing your dodge (it is a dive where you're immobile for a moment) and bombs.
4) Memorize food locations to get health before dying (no checkpoints).
5) You can also hit a chicken to get a random shop which helped me finish this tough first level.
