Hello!
I gave your game a try.
Not gonna lie, it was quite difficult. Took me 5 tries to get through the spikes, that run managed to get a little bit further, got the fire weapon upgrade, then got the normal weapon back, but then losing and starting from beginning again really put me off from playing again. Do you have any checkpoints?
Overall, nice simple game. I was using a keyboard, but I don't think it was the problem why I lost. You can surely make it work with a keyboard.
Ok visuals, fitting music. Not much else to say. Did not encounter any bugs.
Regards,
Remi
