Its a good base for a game so far! just a few things
For starters I think the mousewheel for attacking is unique, but for a gimmick like that i feel its important to mention it somewhere in game. Additionally something I noticed was that enemies would spawn directly over my player, so that was kind of an issue… Overall i think the game just needs a bit more polish, maybe some animation work and more in the sound department would really help in making this game even better
overall very neat little game, a little flawed, but very neat.. can’t wait to see what kinds of works you do ahead! you have alot of potential ^_^
(also, psst… just so you know for the future, the common practice for game exports is to put your .exe and .pck in the same folder, and make a .zip for it to be uploaded online, just saying it so you know for next time :p)
