This game needs a couple of things. Starting characters should be much less random. I should be able to pick my own stats and so forth.
Second, most importantly, KEYBOARD CONTROLS. It's extremely irritating to keep having to switch between keyboard and mouse.
The game feels...sticky. For example: when using the shield, if you attack as soon as possible after another attack, your shield still damages enemies, but you don't dash. When crossing to a new room, you have to let go of the arrow in order to start walking again. And the frame rate of this game seems WAY too slow for something so simple. It clearly needs a lot of optimization.
There definitely needs to be an option to turn off the leaves/particle stuff. And figure out what is hogging all the CPU time in shops. Great otherwise, but I won't be playing it anymore until you fix these problems.
Either powers should use less energy, vials should refill more energy, or there should be more vials. It's really annoying to not be able to do anything interesting because I don't have energy.
Firing is really goofy sometimes. I have to click and hold the fire button for a bit to make sure that it works; if i just click, usually nothing happens.
It still affects your score and over 30 levels it adds up.
