Really neat game. The isometric aspect of the game was a bit awkward to get the hand of for me but I got it down after a bit. The difficulty progression is near perfect apart from the amount of levels with the rotary blades that keep you moving. Whilst I think they're a great addition to the game they can really take away from the great experience I was having previously, but then again it's replaced with another form of difficulty that offers a nice rush when you complete a level.
It's more of a personal thing than anything but I'd appreciate a difficulty selection in a sense, as well as maybe a speedrunner mode? Such as designing levels in such a way where the cannons and spinning axes can be dodged if you attempt to complete the level in an optimal time? Maybe even have a practice mode where you can set the speed of the rotary blades that chase you? Just a few basic ideas is all.
Overall the game has an absolute ton of potential and I could definitely see this being a cool game that could gather a speedrunning community of sorts, great stuff!
