Please explain what exactly the "protection from lightning" upgrade does... because I got it and then ran into a thundercloud and it still hit me and turned my engine off...
I keep removing my fingers from the space bar and it will still mark a pixel when I move to the next space. Very annoying - I'm not actually wrongly marking pixels as I know that something isn't a pixel, it just thinks I'm trying to and then it penalizes me! Also, it is weird that basic functionality (like that it shouldn't mark a wrong pixel when you hold space and move over a square previously marked with an "x") is "unlockable" rather than present from the start, and not until several dozen levels in. Just makes the game more annoying to play in the early levels, which probably isn't really what you want...

Why do I have to click three times to make a move? Click on card, then gap, then card again... I've tried clicking just on card then gap, on gap then card, I've tried dragging... this is inefficient.
Very difficult to tell which tiles are blocked in and which aren't just by looking. I kept clicking on things I thought were open for matching only to find they were blocked in.
It's fairly straightforward until all of a sudden the difficulty level ramps WAY up really fast. Would be nice to have a hint function since I literally see no way to do things after noodling around trying different options for far too long. If you're going to make this hard, then have it be at least minimally challenging earlier on - I look for puzzle games that will make me think but not really break a sweat, and it's frustrating to get so far into one only to discover it's not actually the relaxing kind of puzzle game it appeared to be at first.
I boosted one forge to completion by watching videos to take off half an hour, then started it up again with the intention of doing the same - so I declined to boost it by watching a video. And now I can't watch videos to take off half an hour of time at a go? If you can't do something like this you need to tell people!
...and I finally got the ad viewing to work and the first thing it shows me is a really gross ad for a game where one of the things you can change about your character is her *bust size*. Ew. Maybe work with an ad provider that doesn't encourage the objectification of women?
Two stars only because of adorable doggo. Jumping at the same strength on the same level has different results! If the results are not reasonably consistent then playing this game is entirely chance, no skill.
n/m, i looked again and it does look like trophies. That basically means that whoever is doing the best gamewide just keeps doing better, doesn't it? People who started later than the people at the top of the leaderboards basically have no chance to catch up unless the people at the top stop playing for a looooong time?

As for an ingame hint function: I don't really think it's necessary. You could try asking others for hints in this comment section.
