"THE END" Ending scene looks awesome!
I tried the game a few days ago, got stuck because I moved back to the previous room with the item which gets you small, died and couldn't find it anywhere, or something like that. Don't get me wrong the game had already left me with a strong impression anyway but with so many games I wasn't sure I would try the game again during the jam. Among other things what finished to convince me to try again was when I eventually noticed that you were the team behind Beat Beet ;) .
The game is amazing! It looks awesome and sounds ever better if that's even possible, I love the tunes. It feels so, so good to control and the levels are all excellent with always the perfect difficulty and plenty of little twists which keep you all the more engaged. The fire part in the beginning is so cool, super cartoony, I love it. Finally the NES vibe is about as strong as it can be, in all aspects.
By the way, I saw you also submitted the game to the Metroidvania jam and I don't think exploration on a large scale is even really a thing but on a small scale exploring each zone including through different paths for various reasons is an absolute joy. Note that since it's the NES JAM here ;) the lack of large scale exploration is not necessarily a bad thing, if exploration is going to be linear anyway (because you would need a given ability to unlock the next one, which is not that rare) rather than open then I prefer to simply advance through the zones in order rather than doing useless back-and-fourth.
Thanks for sharing!
