Cute game!
Like the simple graphics and nice tunes.
Not sure why you move with A and D, but level selection left and right key.
Some check points don't work (2d gold level, 2nd checkpoint overwrites all checkpoints, I restarted the level, got 1st checkpoint and died and the game spawned me at the 2nd checkpoint again!) (nope this is the problem with every level, restarting the level doesn't clear checkpoints).
Some levels have one collectible near the end, are they suppose to be golden?
Maybe make some indicator when you have max power on trampoline?
Restart button would be nice.
This part was written as I played:
Last level was really unfair, if you could say that challenge levels where at least skill checks (even if it was getting max trampoline power on the last invisible pixel), castle last obstacle is just stupidly complex. Most obstacles in the castle are stupid because of difference in amplitude, enemy could walk 1 time it's path, when saw would go 2.5 - 3 times all it's path and when you stuck several of them in one path it just became "make lucky shot".
Wait, wtf, does saw speed increased? I watched bigguydev vod and his saws are much slower.
Bro, your speed is connected to refresh rate of the monitor, my second monitor has much slower saws, I am surprised I got to last obstacle on this speed!
