It really felt like you blew your load early, so to speak. 21-30 were nice and challenging, and then 31-50 were all super-easy. Also the scissors achievements aren't very well-tuned -- one would expect successful completion with 100% on all levels to have about the same area trimmed, but I was only at 45% of the gold scissors by the end.
You might want to change the medal "It's a Star". People who didn't look at the medal list before playing level 15 might not know that restarting it triggers something permanently missable.
Guys. It's been almost two months, you still don't have a save button, and your autosave cookie is still broken. You might want to hold off on tweaking numbers and fill that in already.
It's interesting, but the physics can get really cheap. Proxy mines falling from the sky can just randomly veer in random directions faster than you can move away from them.
That was a really unnecessarily long tutorial. Like, Fi from Skyward Sword would be proud. I know how to use a bloody menu, and tooltips would have made almost the entire tutorial completely unnecessary.
You guys really, really, desperately need to move saves to local data. People are used to blocking browser cookies, and Firefox/Chrome will often stop them regardless. This is seriously asking for a lot of dropped save files and wasted time.
The sense of humor is great, but an idle game whose upgrade numbers quickly climb into several hours yet still lacks a save function of any sort is kinda...I mean there's beta, and then there's THAT.
Seriously, the plasma grind is one of the most ridiculous things I've ever seen outside of a Korean MMO. It really feels like you never tested the game without debug settings.
This is horrendously grindy. In large part because your maneuverability is so bad, even with upgrades to both agility and vision, that by the time you can see a patch of stuff that will make it less grindy it's almost always very, very far out of reach.
This is incredibly bland. It's like if someone took Super Mario World, but stripped out 90% of the interesting mechanics and replaced it with grinding coins for crap equipment.
Might want to consider lowering the level 10 quest, since most players are going to be a couple levels lower than that after finishing the game with everything else. Also, you need to script the final boss so neither he nor his tar patches spawn directly on top of you. He instantly killed me twice by teleporting directly into me.
