The game has cool puzzle ideas and tools to solve those puzzles, that said sadly the fact that coins cannot be pickup or earned, will leave you eventually with a softlock and not letting the player progress. Other than this big oversight the game itself was fun to play.
Graphics wise everything we had is okay, I kinda wish breakable walls and rotten boards would be more clear as the challange of a puzzle should not come from me having distinguish two tiles by 8 pixels, but from the mechanics overlapping in the game. It is not a big problem, but something to consider for a future game.
Music and sfx were okay and thank you for the sliders, I do still feel that they are not balanced around each other, minimum volume sfx is still louder than max volume music. Overall not bad, just something to consider yet again for next time.
The ideas here are great, nothing really bad except the softlocks, a little bit more tuning and you have a cool game on your hands! Well done!
