At first I thought this was a bad game because you can't press the jump button right when you land on a spring to go even higher, but then I realized it's a good game because you get to fight some funny little skeletons in it.
tbh i do not like this game very much. it's a very generic platformer where it's big gimmick is that you can switch between modern and retro visuals on the fly. Which is cool but accomplishes very little.
The retro graphics are too excited to pay tribute to the developer's "favorite old-school classics" instead of make the art actually look good in it's own right. They're happy with just making you say "this looks like Mega Man!" or some sh*t. It looks more like Abobo's Big Adventure than it does a real forgotten NES game. Plus, there are clearly a lot of moments that are only optimized for one artstyle. If you're having trouble with any enemy or platforming section and you switch the artstyle, you'll instantly see the hitboxes or platforms become much clearer and easier to deal with. If this had been done as an intentional mechanic ["Travel through time! The version of you from another era can solve puzzles and complete challenges in new exciting ways!"], then we would be better off. As is, the game has two artstyles that aren't great instead of one that is. Good skeletons though.
(EDIT: so i wrote this thinking that Wonder Boy III was not a real game. I thought the devs were trying to do like a cutesy thing where they develop a little indie game and advertise by saying "We're remaking a forgotten gem" but that's just a joke; it's just inspired by that era of platformer. So i was totally wrong in thinking the retro graphics were made in 2017 to look retro. But i like my critiques and kinda stand by them even though I got a basic fact wrong. It is actual Sega Master system art but it does still look like bad generic pixel sprites. I know now that it's not but it still looks like when you see an artist posting pixel art in an Instagram reel and saying "Errrrmm does anyone out there still have nostalgia for the master system days???". The fact that i thought the real 80's pixel art did a bad job of capturing the feel of fun 80's pixel art demonstrates why the game feels soulless and generic to me. I mistook the real thing for a poorly executed tribute and that's a pretty bad sign. )
