Weirdest part of this game is how levelling up makes you worse in every way - all of your abilities drop and you need to raise your stats to return to your former ability line, and as you gain more weapons, it becomes harder and harder to find the upgrades you want in the shop.
How is it games are still being released with the energy mechanic? All it does is penalize players for playing the game, and force them to stop right when they're enjoying it most. Automatic 1 star for the energy mechanic - seriously, if you want us to play the game, let us.
Just did a level perfectly, but since I got all the coins and enemies BEFORE the chest, the level ended prematurely and I got an awful rating. No stars for you until I get to decide when the level ends.
Can't give this game a high rating until it regards the mouse consistently - sometimes click and hold lets me plan a dash, and sometimes it just dashes now, as if I were not holding.
Linux? Could you please try to press any other buttons on your keyboard? Perhaps you have different key codes.
